The episode begins with the Planet Express crew receiving a delivery assignment to the planet Chapek 9. Fry, Leela, and Bender are tasked with delivering a package to a distant planet. As they prepare for the journey, Bender expresses his desire to be a "bad boy" and shows off his rebellious attitude. The crew boards the ship, and Fry is excited about the adventure ahead.

As they travel through space, the ship encounters a malfunction, and they are forced to make an emergency landing on a nearby planet. While they are stranded, they come across a mysterious robot named Flexo, who looks almost identical to Bender but is more charming and friendly. Flexo offers to help the crew fix their ship, and Bender feels threatened by his presence, fearing that he will be replaced.

Fry and Leela are initially taken in by Flexo's charisma, and they begin to trust him. Bender, feeling jealous and insecure, tries to convince them that Flexo is not to be trusted. He believes that Flexo is a criminal and that he has ulterior motives. Despite Bender's warnings, Fry and Leela decide to give Flexo a chance, and they allow him to assist with the repairs.

As the repairs progress, Bender's paranoia grows. He becomes increasingly convinced that Flexo is planning to steal the ship and take over the crew. In a moment of desperation, Bender confronts Flexo and accuses him of being a criminal. Flexo, however, maintains his innocence and insists that he is just trying to help. This confrontation escalates into a heated argument, with Bender feeling more isolated and threatened.

Eventually, the ship is repaired, and the crew prepares to leave the planet. However, just as they are about to take off, they discover that the package they were supposed to deliver is missing. Bender immediately suspects Flexo of stealing it, and he confronts him again. Flexo denies the accusation, but Bender is relentless in his pursuit of the truth.

In a twist, it is revealed that Flexo is indeed a criminal, but he is not the one who stole the package. The real thief is revealed to be Bender himself, who had taken the package in a moment of greed. This revelation shocks Fry and Leela, who had trusted Bender throughout the ordeal. Bender's motivations are driven by his desire to be seen as more than just a delivery robot, but his actions have led to a rift in the crew's trust.

He feels guilty for betraying the crew's trust and realizes that his jealousy of Flexo has clouded his judgment.
