John is taken on a murder-fueled ride by a mysterious stranger that transforms the weak-willed, disillusioned husband and father into a desperate hero willing to go to any length to protect his family.

21 Jump Street is the headquarters for a squad of police officers who specialize in investigations relating to young people. Each of the Jump St. personnel was selected for their ability to pass for high school or college students, allowing them to operate undercover in areas where it is difficult for regular police officers to blend in unnoticed.

What appears to be a random kidnapping becomes something more sinister when Secret Service Agent Jeremy Reins discovers he's being used as a pawn in a terrorist plot. Watching the clock tick down to an unknown catastrophe, Jeremy is forced by his captors to listen to the outside world on the brink of collapse, knowing that the only way to save the people he loves is to divulge a secret that he has sworn to protect.

The narrative revolves around police officer Amadeus Warnebring, tone-deaf scion of a distinguished musical family, and his attempts to track down a group of six guerilla percussionists whose anarchic public performances are terrorizing the city. The drumming set pieces correspond to an avant-garde score with four hilariously titled movements. Where the short involved the six drummers imaginatively using standard apartment furnishings as their instruments, the feature unleashes them on an unspecified city's civic and cultural institutions. Including an amusing backstory for each of the soberly dressed drummers as well as their nemesis, music-hating investigator Warnebring, the film creates a treat for the eyes and ears from the dull, repetitive sounds of everyday life.
