Bender learns that he was never given a backup unit that allows the memories of robots to be uploaded into new bodies when they die, meaning he is not immortal as he always thought. With the help of Hermes, Bender decides to confront his inspector from when he was first manufactured, known to him only as Inspector 5. All information on Inspector 5 turns up missing at the Central Bureaucracy where he worked, so Bender calls Mom's Friendly Robot Company to report his fatal defect. Not wanting a flawed robot to roam around in public, Mom sends killbots after Bender. Bender's and Hermes' escape takes them to Tijuana, Mexico, where Bender was manufactured. Bender goes to Inspector 5's home to find once again that he is not there, and is forced to accept his own mortality. The killbots continue to try and kill Bender until Hermes fakes his death by accessing Inspector 5's database and labels Bender as "terminated", ending the pursuit. Bender returns home with Hermes with newfound pride in his mortality, oblivious as Hermes pulls out Inspector 5's missing profile and burns it, revealing himself as Inspector 5. A series of flashbacks then show how Hermes overrode the baby Bender's defect and quit his job because he could not bring himself to dispose of him, and how he kept all information on his identity a secret during the search with Bender.
