Kevin Fahey was once a second-rate cop, a mediocre husband, and an absent father. But, ever since he was killed in a drug bust gone bad, he's been a lost soul, in limbo, searching, and hoping for redemption. Maggie Gunn, the detective who replaced Kevin on the force, is searching for the murderer of a nurse, in her own home, and the perpetrator of the abduction of a young boy from the park. Kevin helps Maggie, with her investigations, since he can go places she can't, and knows things she doesn't.
