What Season 4 of 21 Jump Street

The fourth season of 21 Jump Street keeps the special unit based in Metropolis, housed in an old church on Jump Street. Its officers look like students and go undercover in high schools and colleges to investigate drug trafficking and other crimes among young people. At the start, Booker solves a case tied to Hanson's release from prison and leaves the police force. The officers must earn their classmates' trust without raising suspicion, and every operation exposes them to risks inside the classroom. Hanson, Penhall, Hoffs, Ioki and Fuller lead cases ranging from designer drug labs to a priest suspected of selling Salvadoran babies. Personal problems mix with the undercover work.
