Jailed on a trumped-up charge near the end of season three, LAPD undercover officer Tom Hanson (
Johnny Depp) is released from prison as
21 Jump Street enters its fourth season. The release has been engineered by Tom's partner, Officer Dennis Booker (
Richard Grieco), who then resigns from the force (the better for actor Grieco to launch his own spin-off starring series,
Booker). Back at 21 Jump Street headquarters, Tom resumes his duties as a member of a team of youthful cops who pose as teenagers in order to root out and bring down adult criminals. As in previous seasons, season four offers an interesting array of guest performers, among them future stars
Robyn Lively and
Shannen Doherty, hearing-impaired standup comedien Geri Jewell, and basketball legend
Kareem Abdul-Jabbar. One episode, "Old Haunts in a New Age," affords the viewer a rare opportunity to see actress
Pamela Segall, who is otherwise best known for her cartoon voice-over work on such animated series as
King of the Hill (in which she essays the male role of Bobby Hill!). Although
21 Jump Street would be canceled by the Fox network at the end of its fourth season, the series lived on for an additional year in off-network syndication. ~ All Movie Guide
