A policeman uses forceful ways to solve crimes.

The only clue in a serial murder case, a trail of police-issued ammunition, leads McCall and Hunter to suspect a colleague.

Hunter and McCall's only lead in an accountant's slaying is his son (Chad Allen), who appears too traumatized to help.

Hunter and Molenski investigate a murder in which the prime suspect is his former partner, an Alzheimer's victim.

Childhood memories of a friend's murder may stand in the way of Molinski's ability to investigate a serial rapist and killer.
