Dexter is stalking his next victim, a drunk driver about to be acquitted for the murder of a teenage boy. But when a fellow cop is found murdered, Dexter has to put that on hold to help Homicide Detectives Batista and Doakes investigate a crime boss suspected of the murder. It gets even more personal when the crime boss also orders a hit on the wife of the murdered cop. Meanwhile, the hooker-hunting Ice Truck Killer strikes again and leaves a macabre piece of evidence that Debra finds, gaining her the transfer she wanted out of Vice and into Homicide.
