Home from Afghanistan, Sam Easton is trying to rebuild a life in his hometown of LA. Separated from his wife, bartending and therapy sessions are what occupy his days and nights. When friend Melody Traeger is beaten by her boyfriend, she turns to Sam for help, but after the boyfriend turns up dead the next day, a hard case like Sam is the perfect suspect. LAPD Detective Margaret Nolan, whose brother recently died serving overseas, can't quite see Sam as a killer. She's more interested in the secrets Melody might be keeping, and in this series debut, it starts to look like there's a connection to another murder case on the other side of town.
