Anakin Skywalker returns to Coruscant and heads straight for the home of his wife, Senator Padmé Amidala. The two of them are happy to finally spend an evening alone with each other.
Meanwhile at the Jedi Temple, the Council is suspicious of Senator Rush Clovis of Scipio, who has strong ties with the Intergalactic Banking Clan. They have asked Senator Amidala, who once had a close relationship with Rush when they entered the Senate together, to spy on Clovis but she has refused. They are trying to ask Anakin to speak to her, but he ironically has been ignoring their calls to spend time with Amidala.
Anakin finally heeds their summons and agrees to help with more than a little jealousy after finding out about the relationship between the two. He re-approaches Padmé, but is unwilling to allow her to approach Clovis again. They get into an argument and Padmé chooses to take the mission after all, partially out of anger at Anakin.
Padmé meets with Clovis in a senatorial café and learns that he is heading to Cato Nemoidia to deal with members of the Trade Federation. He invites her to come with her, hoping to rekindle their relationship.
As they board the transport to Cato Nemoidia, one of the pilots turns out to be a disguised Anakin along with R2-D2.
On Cato Nemoidia, Clovis and Padmé meet with the Trade Federation senator Lott Dod. The Banking Clan is indeed investing in a massive droid factory on Geonosis, the planet where the Clone Wars first began. After being shown to her room, Padme walks around the estate, where she nearly walks in on their meeting with Poggle the Lesser. She just misses getting a good look at the hologram of the factory and is escorted back to her room after by Clovis. Dod and Poggle plot to poison Padmé in order to use an antidote as leverage against Clovis for a greater share of the profits from the factory's operation.
At dinner, Dod spreads poison on the lip of a goblet before offering it to Padmé. After the meal, it starts to take effect. She shakes it off as Clovis sends C-3PO away to escort her around the grounds. As Threepio returns to their quarters, he runs into Anakin. During the tour, Padmé gets Clovis to bring her a drink as the poison continues to slowly affect her. She goes to the alcove where she saw Dod and Poggle speaking with Clovis and manages to reactivate the hologram, containing the coordinates of the factory, and take the hologram disc. Just as Clovis returns, followed shortly by an angry Anakin, Padmé collapses from the poison into Clovis' arms and is just barely able to get the holodisc to Anakin. Anakin gives the disc to Artoo and rushes back.
Meanwhile, Clovis confronts Lott Dod, who accuses her of being a spy. Clovis finds the disc missing and confronts Padmé about it, who readily admits to it. He tries to convince a newly-arrived Anakin to exchange the disc for Dod's antidote. Anakin forces him to help carry Padmé back to her ship. Confronted by Dod and his aides, Clovis pulls a blaster on the senator and forces him to give him the antidote. Anakin takes Padmé and the antidote onto her ship and takes off with the plans, leaving Clovis to face an angry Lott Dod.
- Alliterative Title: "Senate Spy".
- Call-Forward: At one point, Anakin uses "klick" (slang for kilometer) in the context of a unit of time ("[I had to report to the Council] seven klicks ago"). Famously, in A New Hope, a similar goof was made by Han Solo (boasting of making the Kessel Run in less than twelve parsecs, which is also a unit of distance).
- Crazy Jealous Guy: Anakin, although he mostly manages to keep his temper in check.
- Even Evil Has Loved Ones: Clovis feelings for Padmé are entirely genuine, and he unhesitatingly sacrifices himself to save her.
- Impractically Fancy Outfit: The dress Padmé wears to dinner, with its ridiculous tiny front-only bodice and detached sleeves with large skin-revealing holes in them, would require copious glue or tape to stay on and be incredibly uncomfortable and difficult to move in without having a wardrobe malfunction.
- Ironic Echo: "Duty comes first, especially in wartime."
- Multitasked Conversation: After Padmé steals a data disk containing plans for the Separatists' new droid foundry, Clovis abruptly returns to the library with the drink she sent him for. After drinking, she gives Clovis a hug when he asks for her hand, just as Anakin arrives in response to her signal. Padmé signals him to retrieve the disk by waving it in her hand while saying "I've been waiting for this moment all night", which Clovis, unaware of the Jedi behind him, takes as a romantic overture.
- Nice Hat: Lott Dod wears a mitre nearly half his height.
- Noodle Incident:Anakin: I had to hitch a ride on a cargo freighter.
Padmé: What happened to your military transport?
Anakin: Ahhh it blew up.
- Old Flame: Rush and Padmé were very... close once.
- The Password Is Always "Swordfish": The passcode for the holotable containing the droid factory plans is "Padmé". It seems that Clovis has had feelings for her for a long time.
- Poison-and-Cure Gambit: Lott Dod attempts this by poisoning Padmé so he can use her as leverage against Clovis.
- Poor Communication Kills: Padmé at first refuses to spy on Clovis only because the Council didnt mention he was potentially The Mole. When Anakin accidentally mentions this casually, she immediately changes her mind.
- Sexy Backless Outfit: The dress Padmé wears to dinner to try and take advantage of Clovis' feelings for her has no back, detached sleeves, and the bit of bodice it has seems to be held on with tape and wishes.
- Tampering with Food and Drink: Dod poisons Padmé by poisoning a goblet before she drinks from it.
- Throw 'Em to the Wolves: Motivated mostly by jealousy, Anakin leaves Clovis to face Lott Dod, Poggle, and a squad of battle droids alone, even after Clovis had helped him and kept up his end of the bargain. Hey, he is the future Darth Vader, after all!
- Unlimited Wardrobe: Padmé changes her outfit four times over the course of the episode.
