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.

Hanson and Penhall probe a student auto-theft ring; Hoffs must befriend a husband-hunting Polish exchange student.

Romance complicates Hanson's investigation into student sales of stolen goods.

Penhall and Hanson enter an elite prep school to investigate a girl's death and discover an on-campus drug operation.

Penhall poses as a high school ballplayer to protect a star pitcher, the son of a gangster who became a government witness.
