Blackadder: But that's impossible, your Highness. Only I have the key to your sock drawer.
An inside job is a crime, usually larceny, robbery, or embezzlement, committed by a person or persons in a position of trust who is authorized to access a location or procedure with little or no supervision, e.g., a key employee or manager. The perpetrator can also be a former employee who still has specialized knowledge necessary to facilitate the crime.
Pulling off The Caper can be quite difficult even for an expert criminal. Guards can have unpredictable schedules. There are likely to be alarms and other security systems with which they are unfamiliar, or even completely unaware of. And there's always the possibility that they stage a successful break-in, only to discover the MacGuffin has been moved elsewhere.
All of the above wrinkles are made at least a little smoother when the perpetrator has an insider's knowledge of the target, or even the authority to make changes (to guard schedules, security systems, etc.) to make the target more vulnerable. This perpetrator may be a lone operator pulling off a plan of their own design, the mastermind of a team of crooks, or an "inside man" in the employ of a third-party accomplice or accomplices. If the latter, they may be a willing participant or the victim of blackmail, Mind Control, or some other means of coercion.
Can overlap with The Mole when the inside man is part of an external criminal organization. Inside jobs are a common method of pulling off The Caper, with the inside man consequently being a member of the Caper Crew.
Note: as a trope dealing with betrayal, expect spoilers to be unmarked!
- Scorched details three different plots to rob a bank, all of which were initiated by bank tellers.
- The mastermind behind the mall robbery in Paul Blart: Mall Cop turns out to be one of Blart's trainees.
- Averted, despite the title, in Inside Man. The ending reveals none of the robbers were bank employees.

- The Town:
- Subverted. The robbery at Claire's bank did not involve an employee accomplice but the cops think that there might have been one. When Claire quits her job, it raises red flags and when her relationship with Doug is discovered, she is accused of being that accomplice even though the audience knows she is innocent.
- Played straight as well. The later robbery at Fenway Park involves an inside man, a Fenway employee who owes Fergie a lot of money and hopes to wipe out his debt by providing the robbers with access to the money room.
- In Armored six security guard working for an armored truck company decide to steal the money they are guarding and make it look like they were robbed while transporting the money to its destination. They figure that if all of them are part of the theft, then no one needs to get hurt. However, things do not go according to plan, a witness is killed and one of the guards decides to stop the others any way he can.
- In Cliffhanger the bad guys rob a US government plane transporting $100 million in uncirculated $1,000 bills while it is flying over the Rockies. This daring and extremely dangerous heist is only possible because one of the federal agents guarding the money is actually working for the bad guys and kills the other guards.
- The film Flawless (starring Michael Caine and Demi Moore) follows the plan of a diamond exchange house's elderly janitor (Caine), who after his many years attending to the place knows its every security flaw.
- In The Score Jack plans to steal a priceless scepter from the Montreal Customs House. He gets a job as a janitor in the Customs House so he has access to the building and can see the security measures first hand. He even goes as far as to pretend to be mentally disabled so he appears harmless and beneath suspicion.
- Deep Rising: Finnigan eventually figures out that Hanover was working with someone on the cruise liner for the planned heist that never materialized. That person turns out to be Canton (the ship's owner), who was responsible for sabotaging the ship's systems before the monster happened to show up. His motive was to sink the ship so he could reap the insurance money since they were actually operating at a loss. This revelation infuriates the Captain, since it's entirely Canton's fault that they couldn't get out a distress signal.
- The Lookout: The entire plot revolves around a bank robbery where the would-be robbers have to convince Chris, a young brain-damaged guy who works there as the janitor, to cooperate with them. They do this through a combination of the promise of financial reward, painting it as something daring to do to get out of his currently crappy life, and some feigned romantic interest from their pretty female accomplice.
- In Thunderball, SPECTRE co-opts a NATO officer to steal a pair of nuclear weapons. This was subverted in the film version of Thunderball, where SPECTRE replaces the officer with a double, but played straight again in the remake, Never Say Never Again, where the officer reprogams two nuclear missiles so the warheads can be recovered by SPECTRE.
- In both the novel and film Jurassic Park, the plot is kicked off by park employee Dennis Nedry sabotaging the park's security systems in order to facilitate his theft of dinosaur embryos to sell to Biosyn, one of Ingen's competitors.
- Referenced but averted in Jumper. Davy cleans out a bank vault with his teleportation power. Later, somebody theorizes in his hearing that the robbery must've been an inside job since there wasn't any sign of forced entry.
- In "Silver Blaze", two of Sherlock Holmes' hints are "the curious incident of the dog in the night-time" (it was completely silent) and the fact that powdered opium was put in a dish spicy enough to hide its taste. Both point at an inside job, because a dog would not have kept silent had it sensed an intruder, nor could an outsider have arranged for a spicy dish to be served on that particular night.
- Wet Desert: Tracking Down a Terrorist on the Colorado River: The bomber disguised himself as a member of the Bureau of Reclamation when targeting Davis Dam, making Grant suspect it may be an insider at the Bureau.

- It comes out that Gus Fring's operation is supplied with methylamine by Lydia, who facilitates its theft from her employer, Madrigal.

- In one episode of It Takes a Thief (2005), Jon is charged with robbing a mechanic's business (as opposed to houses like the show normally covers). Rather than risk setting off the alarm and having to pick a lock, Jon just bribes an employee to not set the alarm and unlock the back door. Naturally, with all the security features disabled, Jon effortlessly cleans the place out.
- One episode of Monk features this trope taken to its logical extreme. Monk's bank is robbed and he goes undercover as a guard to crack the case.

They find out that he is about to guard a very valuable platinum shipment and they suspect that the shipment will be attacked by robbers who are likely to kill the guards.

- The Equalizer. Robert McCall is protecting a witness being harassed by the ex-con he testified against. McCall says the ex-con's actions seem to be Disproportionate Retribution, so the witness admits that he was in on the crime. When the robber was caught, he identified him in a line-up because he was afraid the police would discover his own complicity.
- NCIS has an attack on an internet server farm in order to bug the facility. The inside man is a security guard who allows himself to be shot to make himself look like a hero instead of The Mole.
- NCIS New Orlean has the episode "In the Blood" where the NCIS NO office investigate the robbery of a casino many years ago in relation to Pride father, Cassius, being involved (somewhat) with the $3 million that went missing.

Being a prominent member of the Guild yourself at this point in the quest line will help you avoid any suspicion.
