After a high school boy gets shot dead, the Jump Street team is called in to solve both his murder and the more general problem of the drug-dealing and gun violence in the high school. Hanson goes undercover as a (drug-dealing) high school student, and tries to get close to the drug-dealing thug Ronnie Seebok.
Judy does not go undercover in this episode, but as a police officer tries to connect with the girlfriend of the murdered boy in order to solve the case, in hopes that the girlfriend knows more about the murder; unfortunately, the girlfriend doesn't, and turns out to be a drug user herself.
Penhall, in another aversion of the series' usual "undercover" plot, is sent to work as a uniformed patrol police officer in the same neighborhood. He soon begins to suspect that his assigned partner is a corrupt cop.
Meanwhile, Ioki, due to a computer failure / administrative mix-up has all evidence he ever existed deleted, which is played for laughs.
- Broken Pedestal: Penhall says he wanted to be a cop like Adabo, before he suspected him of corruption.
- Dirty Cop: When Penhall has to go back to uniformed patrol, the partner he gets assigned to, Officer Adabo, turns out to blackmail junkies into lending (probably "giving") him money and to even kill suspects by pushing them off a roof. The latter part becomes a major plot point in the 2nd half of this 2-part episode.
- Dude, Not Funny!: Hanson and Penhall make fun of Ioki due to the fact that due to a database/computer failure, evidence of the latter's existence is erased. Ioki reacts not amused, but hurt by that:Penhall: [To Ioki] You don't exist? [To Hanson] Hey did you hear something?Ioki: Hey, that's NOT FUNNY!
- Foreshadowing: maybe - it's unknown whether the showrunners planned it this way or not - but the sub-plot of Ioki being 'erased' foreshadows the revelation that he's actually living under a false identity; he falsified his identity as a Japanese-American to become a police officer, believing a Vietnamese refugee would never be accepted into the academy.
- Unperson: Due to an administrative failure, all evidence of Ioki's existence as a person is erased, and Ioki mainly spends this episode trying to convince administrative personnel that he does exist
