[[caption-width-right:350:Hey, Picard; you know that demonic temptress who wields godlike power and has legally enslaved an entire planet of people? [[AbhorrentAdmirer I think she's into you.]]]]

'''Original air date:''' February 4, 1991

Data is performing a scene as Ebenezer Scrooge in a ''Literature/AChristmasCarol'' holoplay for Picard, who gives him a glowing review. Data states that he'd like to try Method Acting to gain a better understanding of human emotions. Picard is then called away as the ''Enterprise'' receives a distress signal from a Federation science station on Ventax II. The station's director, Dr. Clark, explains that the station is being attacked by the planet's populace, which has erupted into chaos over a belief that their world is about to end. Once the ''Enterprise'' arrives at the planet, the Ventaxians break into the station, and Dr. Clark is beamed aboard in the nick of time. Unfortunately, the rest of the scientists are taken hostage by the mob and the ''Enterprise'' can't get a lock on them.

In the ready room, Dr. Clark explains that the Ventaxians were a highly advanced civilization until 1,000 years ago, when they suddenly turned their backs on technology and reverted to an agrarian society. Despite their low tech level, Clark describes their society as idyllic--until a few months ago, when the people became increasingly obsessed with the legend of Ardra, the Ventaxian Devil figure who promised the people 1,000 years of prosperity in return for the planet's enslavement 1,000 years later. That was precisely 1,000 years ago. The crew beams down to the planet in an attempt to release the hostages and talk sense into the mob. The planet's head of state, Acost Jared, says that there's nothing he can do, as all the signs pointing to Ardra's return have occurred, including earthquakes and visions of the woman herself. As if on cue, a woman materializes in their midst and states, "Time's up!"

The woman starts talking and walking around like she literally owns the place, demanding a full census of the population with emphasis on productivity and economic forecasts. She takes special interest in the Starfleet crew, especially Picard himself. When questioned about her identity, she states that she is indeed Ardra as well as the devil figure on countless other worlds, changing her shape to demonstrate. Picard still isn't buying it and demands to see the original contract that bound the world to Ardra. Ardra magnanimously frees the Starfleet hostages, but Picard decides that he will not abandon the world to "that woman." He sets Data to examining the contract and beams away.

In the conference room, the crew discusses the possibility that Ardra is a member of the Q continuum--or even Q himself, disguised as a woman for kicks. Picard points out that Q wouldn't care about contracts or economic forecasts; he is convinced that the woman is a simple ConArtist, with tricks that can be easily accomplished via technology, seeking to take advantage of the legend of Ardra to take over the planet. Returning to the bridge, Picard orders a search for a possible base of operations, but stops short when he sees Ardra herself, sitting in Picard's chair. Worf tries to remove her, but ([[TheWorfEffect predictably]]) ends up bouncing off a force field. Data returns to report that Ardra's contract is ironclad. Ardra states that it also gives her claim over everything in the planet's airspace and orbit--including the ''Enterprise''. Data confirms that this is true.

As Data continues to study the Ventaxian legal system, Ardra begins trying to seduce Picard, showing up in his quarters and changing her shape in an attempt to please him, but he rejects her. She teleports him to the starbase in his pajamas in retaliation, surprising Geordi and Clark, and disabling the transporters, forcing Data to pick him up in a shuttle with a spare uniform. En route back to the ship, Data relates that he found a legal precedent involving a contract dispute between a Ventaxian and a Klingon craftsman, where it was decided that due to one of the parties being alien, it was a matter for arbitration and not the courts. Picard notes that this is just what they need and that they will be able to lure Ardra into it by playing a con of their own... Unfortunately, as they're discussing this, the ''Enterprise'' suddenly vanishes.

Geordi tries to locate the ship but can't find it anywhere within one light-year. However, he did notice a jump of {{Technobabble}} Particles and claims that if they can get Ardra to do some more of her tricks, they might pinpoint her power source. Picard then goes to Ardra and explains the arbitration precedent. Ardra doesn't see why she should agree to this, prompting Picard to promise her a legendary priceless jewel if she wins. Ardra isn't interested and proposes a different offer: Picard himself, "heart, mind and soul." Picard reluctantly agrees, leaving only the matter of who should be the arbiter: Ardra chooses Data, under the rationale that as an android he is incapable of bias. Data takes Picard aside and confirms that he would not give Picard any special treatment should he be appointed, but Picard agrees on the principle that Data is the only person on the planet whom Ardra cannot intimidate.

The trial... er... arbitration of the century then begins. The beginning doesn't go well, since Ardra manages to use a few iffy yet acceptable-under-Ventaxian-law arguments, as well as intimidate Jared (the sole witness) to "prove" that she is indeed Ardra. At one point she demonstrates her powers again (testing Data's patience) and asks Picard if he can explain them. Picard cannot. Meanwhile, Geordi and Clark {{technobabble}} their way through tracking Ardra's power source with little success.

Picard decides on a different approach. Unable to prove that she is not Ardra, he disputes her involvement in the bettering of Ventaxian society in the 1,000 years that followed the dark days that prompted the deal. By questioning Jared, Picard proves that all of the improvements were made by the Ventaxians themselves without any help from Ardra. However, Ardra responds by asking Jared if the terrible conditions would have continued had she ''not'' intervened. Jared replies yes. This is taken as evidence that the contract was fulfilled.

Things look pretty grim for Picard until Geordi enters the room and Picard asks for a recess, under the guise of Geordi bringing evidence for review. Geordi explains that they have tracked the power source: a ship equipped with a "bad copy" of a Romulan cloaking device parked near the planet's magnetic North Pole. The ''Enterprise'''s "disappearance" was accomplished by simply extending the cloaking field over it. Geordi has contacted the ship, and Picard and Geordi hatch a plan...

The arbitration resumes. Picard claims that Ardra has no powers whatsoever and decides to prove it by "stealing" them. Picard then causes some earthquakes of his own, makes Ardra disappear, and assumes the guise of Fek'lhr, all of which Ardra is powerless to stop. Picard explains that the ''Enterprise'' has seized control of her ship, where all the technology she used to perform her tricks was held. He also reveals that "Ardra" was telling the truth when she claimed to have many names: her crew revealed she's used 23 aliases in that sector alone. Data declares the contract dissolved and "Ardra" is arrested. She claims Picard would have "more fun" if he had lost and gives an "until we meet again."

The Ventaxians thank Picard for saving them; Picard responds that they themselves are truly responsible for saving themselves, while he just exposed a fraudster. He and Data exit, roll credits.

!! This episode contains examples of:
* AbhorrentAdmirer: How Picard sees Ardra. Not that she's really ugly... [[HotAsHell far from it]].
* ActorAllusion: At the start of the episode, Picard is enjoying Data's performance as Ebenezer Scrooge. Around the time this episode aired, Creator/PatrickStewart had appeared on Broadway doing a one-man stage adaptation of ''Literature/AChristmasCarol''.
* ApocalypseAnarchy: Dr. Clark and his team get caught up in a riot, and Jared mentions that more chaos is going on.
* ArbitrarySkepticism:
** Ardra accuses Picard and company of this, since despite all the incredible and varied things Picard and the crew of the ''Enterprise'' have seen over the course of their careers, ''no-one'' ever considers the possibility that Ardra is what she claims she is. They briefly consider that she may be Q (or ''a'' Q), but dismiss it on the grounds that no Q would be interested in a planet's economics. It may be, however, that it's ''because'' of this experience, where all claims of supernatural beings always turn out to be some variety of SufficientlyAdvancedAliens, that they doubt her.
** Ardra repeatedly demonstrates a lack of any kind of extrasensory abilities. She did not know about the Federation hostages, requires a census of the population as well as economic forecasts, is unaware that Data is an android until told, and just generally asks a lot of questions that one would expect a genuinely godlike being to already know the answers to. This is an obvious tipoff that she is neither the "devil" nor an advanced alien. Ardra also flubs Klingon mythology by saying that Fek'lhr was the Klingon devil (he's not, Klingons have no devil.)
* BadassFingersnap: Picard does this when turning Ardra's "powers" against her. Q would approve.
* BigRedDevil: When Ardra claims that IHaveManyNames, she says "Devil" is one she hasn't heard in a long time. Later on (presumably after doing some research on Earth mythology), she transforms into a classic scarlet-skinned devil in an attempt to intimidate Picard.
* BlatantLies: When Picard asks Ardra to stop the tremors he caused (having confiscated her ship), she claims "I like the tremors!"
* BullyingADragon: One has to wonder what Ardra thought was going to happen when she decided to mess with the Federation's flagship and its most accomplished crew, since she isn't what she claimed to be.
* ClarkesThirdLaw: {{Played with}}. Ardra's tricks are performed using technology, but it turns out to be technology that the ''Enterprise'' itself possesses (or at least knows of), dressed up to look more impressive than it is. (And the head scientist at the station actually being ''[[MeaningfulName named]]'' Clark is very likely a sly nod to this.)
--> '''Picard:''' Her powers are, at the best, unclear. Think about it, Mister Worf. Transporter technology can make things appear and disappear. The illusion that she can transform herself into a Klingon creature could be created by holographic projection.\\
'''Clark:''' And creating a minor tremor could be the result of a low frequency tractor beam projected against the tectonic plates.\\
'''Picard:''' We are capable of recreating all of these events. It's just that she dresses them up and she delivers them with more dramatic flair.
* ContinuityNod:
** Worf isn't fully successful at hiding his nervousness when Ardra takes the form of Fek'lhr-- after all, he tortures the dishonored dead in Klingon mythology, and Worf is [[Recap/StarTrekTheNextGenerationS3E17SinsOfTheFather still suffering under discommendation]]. By Klingon standards, he's headed straight to Hell if he should die.
** In the TOS episode "[[Recap/StarTrekS3E7DayOfTheDove Day of the Dove]]", Kang told Kirk that the Klingons don't have a Devil. In this episode, Fek'lhr is ''not'' the Klingon Devil; he is the guardian of Gre'thor, the Klingon Hell, similar to Cerberus from ancient Greek Mythology.
* CourtroomEpisode: With Data as the utterly impartial arbitrator. It makes you wonder if any other civilization has thought of using androids for arbitrators or judges.
* DealWithTheDevil: The whole situation rests on the claim of a deal with Ardra that the Ventaxians made with her a thousand years ago that she would give them a thousand years of peace and prosperity in exchange for her enslaving the entire populace when the time period expired. The criminal known as Ardra appears at the present time to take advantage of this to make the planet surrender its resources to her.
* DontCallMeSir: Ardra, despite enjoying her power over the Ventaxans.
--> '''Jared:''' Ardra, most powerful one, I am Jared, Leader of Ventax Two. I take responsibility for all that displeases you. Please, do not punish my people.\\
'''Ardra:''' Punish? Who said anything about punishing? I merely expect your end of our contract to be upheld.\\
'''Jared:''' Thank you, Ardra.\\
'''Ardra:''' And don't talk like some ancient prophet around me, with "thee's" and "thou's" and "most powerful one's". It was appealing for a few centuries, but I bore easily. And stop cowering. When I want you on your knees, I'll let you know.
* TheDreaded: Ardra has an entire planet quivering in fear at her very mention.
* EvilIsHammy: Ardra ''relishes'' her power over the Ventaxians and putting the moves on Picard. She seems to prefer the ColdHam variety-- she comes off soft-spoken and doesn't raise her voice too much, but she definitely carries herself like an EvilOverlord.
* FamousFamousFictional: During the "Christmas Carol" cold open, Data mentions three of his "mentors" in Method acting: [[https://en.wikipedia.org/wiki/Konstantin_Stanislavski Konstantin Stanislavski]], [[https://en.wikipedia.org/wiki/Stella_Adler Stella Adler]], and Garnav.
* {{Foreshadowing}}: Data's rehearsal of the [[Literature/AChristmasCarol Jacob Marley]] scene at the beginning introduces the two main themes of the episode: the power of fear, and how far you should trust what your senses tell you.
* TheGhost: We never see Ardra's ship or the crew helping her pull off the whole flimflam.
* GodGuise: The criminal claiming to be Ardra has assumed the identity of the Ventaxian Devil.
* HamToHamCombat: In the courtroom. Ardra is condescendingly sweet and pulls out her tricks, while Picard takes the role of a melodramatic lawyer. When deconstructing how "responsible" Ardra is for the planet's recovery, for example:
-->'''Picard:''' ''[while making [[http://tng.trekcore.com/hd/albums/season-4/4x13/devils-due-hd-376.jpg this face]]]'' Did she not pick up even ''one piece'' of ''trash?!''
* HolographicDisguise: Some of Ardra's tricks involve this, including temporarily taking over the appearance of an ''Enterprise'' bridge crew member. Picard uses this knowledge at the end during the arbitration by taking on the form of Fek'lhr with the same technology.
* HotAsHell: Ardra wastes no time flaunting what she's got.
* {{Hypocrite}}: When Picard "steals" Ardra's powers, Ardra appeals to the judge despite having used the same antics earlier. Data declares that [[LampshadeHanging under the circumstances, Picard is allowed some leeway]].
* IgnoreTheFanservice: Picard isn't even the least bit tempted by Ardra.
* IHaveManyNames: Ardra boasts this in her role as TheDevil. Interestingly, this turns out to be true, though only in her criminal career.
* InvisibilityCloak: Part of Ardra's bag of tricks. Turns out to be of low enough quality for Geordi to [[SeeTheInvisible penetrate it]].
* IronicEcho: A visual one: when Picard "steals" Ardra's powers, he replicates a trio of her prior tricks: First, he causes an earthquake (which Ardra can't stop), then he makes Ardra disappear briefly, and finally gives himself the guise of Fek'lhr.
* {{Leitmotif}}: Ardra has her own little theme tune, slightly seductive and somewhat creepy that plays whenever she appears unexpectedly on-scene.
* LoopholeAbuse: Heroic variant: "Ardra", after being outed as a con artist, withdraws her claim to the planet. It's for this reason ("the advocate's withdrawal") that Data declares the contract null and void, even though "Ardra" is not the actual advocate as has just been proven. (It's not a loophole so much as an unenforceable contract, since no one else claiming to be Ardra showed up to stake her claim to Ventax II when the time came. Since the sole claimant has been exposed as an impostor, the contract is dissolved.)
* MagicFeather: Picard argues that the original deal with Ardra was a case of this, as there are no records of her actually helping to create the Utopian society the Ventaxians now enjoy, and their history actually indicates the idea of the deal helped the people put in the hard work necessary to create it themselves. Ardra doesn't dispute this, but argues it's irrelevant; the deal never specified how the planet would improve, only that it would.
* NiceJobFixingItVillain:
** Ardra's tricks in the courtroom leave enough of a signature for Geordi and the Federation scientists to track.
** For that matter, Ardra's insistence on messing with the ''Enterprise'' rather than sticking with conning the Ventaxians does nothing but reinforce Picard's determination to expose her.
* NoSuchThingAsSpaceJesus: Ardra turns out to be a regular human or alien using advanced technology to pose as a god.
* SatanicArchetype: Ardra proclaims to be ''several.''
* ScoobyDooHoax: A 24th century version, as all of Ardra's tricks are merely the use of transporters, tractor beams, cloaking fields, and holography.
* SecondComing: Of Ardra, which the criminal posing as her takes advantage of. Interestingly, this Second Coming is a ''bad'' one; the one coming back is a SatanicArchetype here to collect on a society-wide DealWithTheDevil.
* ShoutOut: After Ardra [[EvenEvilHasStandards orders the release of the Federation hostages]], Picard contacts Dr. Clark to let him know they're being freed, who responds "You did it, Captain. Thank goodness." Picard replies, "[[Creator/MaeWest Goodness had nothing to do with it.]]"
* SpeakOfTheDevil: The Ventaxians consider it unlucky to speak Ardra's name aloud.
* UnspokenPlanGuarantee: Picard tells Geordi he has a plan, but they have only one hour to prepare. The scene immediately cuts to an hour forward, and we see their plan being put into action.
* VaporWear: The outfit Ardra dons when she transports into Picard's quarters to seduce him is practically transparent. [[IgnoreTheFanservice It doesn't work]].
* VillainBall: Though Picard was incited to meddle already (despite his claim of only caring about the hostages at first), Ardra goes out of her way to involve the already-suspicious Enterprise in her con, up to and including attempting to lay claim to the ship, all but ensuring that Picard would have to unravel her deception in order to settle the issue.
* VillainousCrush: Ardra makes it quite clear how attracted to Picard she is. Unfortunately for her, the feeling isn't mutual. Still, she does whatever she can to make him hers.
* WeWillMeetAgain: Ardra threatens Picard with this as she's taken away. While she never returns in the TV series, she does appear in a three-part story in the comics published by DC and the ''Literature/StarTrekPrey'' novel ''The Hall of Heroes''.
* WholePlotReference: The episode is a 24th Century retelling of "Literature/TheDevilAndDanielWebster", with Ardra as the Devil, the Ventaxians as the defendant, Picard as the attorney.
* TheWorfEffect: Worf is summoned to throw Ardra off the bridge and is so out-matched she doesn't even have to stand up. She just sits there as Worf bounces off her invisible force-field.
* WrongAssumption: A subtle case as Picard doesn't actually mention anything about it, but Ardra assumes that Troi is the crewmate he's attracted to rather than Dr. Crusher.
