When a school shooting occurs twice in one month at his daughter's school, Nick is determined to find the shooter and to keep Zara safe. But what he doesn't expect is for the case to be brought to Special Victims, after a past rape victim insists that the shooter is actually the man who raped her and got away with it, and he's come back to finish her off. Will the detectives be able to find the perp before he commits another horrendous crime or puts the whole school in danger? Meanwhile, Nick is torn between the two women in his life when Maria comes for an unexpected visit. He loves Amanda, he knows that, but could he really pass up a second chance with Maria, a chance to start over and be a family again?
