21 Jump Street - Synopsis

Synopsis

Police officer Tom Hanson runs into trouble on the job because he looks younger than he is. At the end of the episode, he is offered a chance to work with other young-looking cops who go undercover in local high schools.

Season 4 was the last season to air on the Fox Network. In commentary on the Season 5 DVD set, Peter DeLuise said that Fox had decided to cancel the show after Season 4 because the ratings had fallen below a set limit. Following this season Johnny Depp and Dustin Nguyen left the show. The departure of their characters was never explained in the narrative of the TV series, but in the movie it is explained that Hanson was transferred to the DEA and was later joined by Officer Penhall. The Booker spin-off crossover episode, "Wheels and Deals Part One", is included with 21 Jump Street's syndication package, and is also included on the fourth season DVD set.

Officer Dean Garrett (David Barry Gray) makes his first appearance in "Everyday is Christmas". As it became harder for the original cast members to plausibly pass as high school students, his character and Officer Kati Rocky (Alexandra Powers) were intended to be "youthful" replacements, so the show could maintain its original premise of younger looking cops posing as high school students.
