After Ali hits a young boy with her car after having a fight with Simon, she soon finds herself not only fighting to prove her innocence, but also fighting to get her job back, which she was stripped of without her knowledge while on vacation. Cold Squad has been turned into a provincial task force, and the only member of the old guard left is Logozzo, so Ali has to prove herself to Coscarella, the new sergeant in charge.

Ali and Frank are assigned to find out who murdered plastic surgeon Marvin Michaelsen after a drug dealer identifies him as the man who removed his fingerprints, but the tension between the two soon ends up taking a higher priority than the investigation. Nicco and Mickey work together on the case of Dermot Wells, a garbage collector that is believed to have murdered his former co-worker, and make a bet on how soon they'll get a confession.

Nicco and Ali investigate the unsolved murder of Jeff Steeves, AKA. Vulse G, after a car is found underwater. The car leads them to an elderly woman named Clarice Fry, which eventually leads them back to her grandson Timo, who has a connection to Jeff's former manager, Desecrate. Mickey is assigned to work the case of Lester Graham, a gambler who owed $20,000 to an on-line gambling company who is rumored to be very violent in their collection methods. Mickey is upset when Bailey asks her to San Francisco then takes his wife instead, but shrugs it off to Nicco.
