Dexter is called in to help Debra with the investigation into the Ice Truck Killer's latest murder, while Dexter hunts his latest victim, a teenager named Jeremy who is a recently released murderer who looks like he's about to kill again. Despite Debra and Dexter's protestations, Lt. LaGuerta starts a manhunt for Tony Tucci, the nightwatchman videotaped at the ice rink where body parts were found. But while the manhunt for Tucci begins, a skeptical Debra keeps looking for the "real" Ice Truck Killer.
Meanwhile, Doakes decides to go after the crime boss at his church, confronting him and his daughter about his part in the murder of a cop and his wife. Rita, Dexter's girlfriend, has her own troubles when someone from her incarcerated husband's past comes to visit, demanding repayment of drugs lost by her husband.
