Crime in school is bad, so to combat it, LAPD higher-ups decide to send four young-looking officers to high school to pose as students. Cops Tom Hanson, Doug Penhall, Judy Hoffs and Harry Truman Ioki are the "lucky" ones chosen to experience the part of their lives they hoped they'd left behind forever.

The CIA recruits Hanson; the squad investigates production of "designer" drugs in a university lab.

Hoffs and Fuller pose as student and teacher to find the witness to a high-school instructor's murder; guest Kathryn Leigh Scott.

In a flash forward to the future, a young police officer who wants to revive the Jump Street program interviews the now-retired cops.

Hanson asks a juvenile on death row to make a video to deter other youngsters from crime.
