21 Jump Street (Seasons 1–5)

21 Jump Street (1987) — watch online on iFILM, the Fox crime drama that launched Johnny Depp's career. A special police unit recruits young-looking officers and sends them undercover into high schools to investigate crimes involving teenagers. Captain Fuller runs a tight team; the cases range from drug rings in gym class to gang violence and peer pressure that turns deadly.

Depp played Officer Tom Hanson for the first four seasons, and the show built a following around his reluctant undercover work and the moral weight the scripts put on teenage choices. It ran from 1987 to 1991, five seasons on Fox — one of the network's earliest breakout hits.

The series tackled harder material than most prime-time drama of its era and held its tone without tipping into afterschool-special territory. Watch all seasons of 21 Jump Street online on iFILM.
