The Squad helps prevent a $1 million heist masterminded by an ex-con whose pregnant wife is an unknowing victim of cervical cancer.

Six years after the last known case, Pete, Linc and Julie are called back to team up again after several attempts are made on the life of Adam Greer, their former commander, now a Deputy Chief in the LAPD and on the verge of retiring. However, they soon discover that the attempts on Greer's life were a ruse to draw them out, and that they themselves are the real targets of the would be killer.
