Forensic analyst Dexter Morgan hides his double life as a vigilante serial killer from his vice squad officer sister, his co-workers at the Miami Metro Police Department, and his commitment-minded single-mum girlfriend.

Dexter's world is rocked when a rival serial murderer, dubbed the Ice Truck Killer by the media, privately contacts him and reveals that he knows Dexter's grisly secret. Meanwhile, Dexter's sister Debra is transferred to Homicide.

The Ice Truck Killer begins leaving body parts from his victims at sites that relate to memories from Dexter's childhood, forcing him to confront his dark personal history.

The Ice Truck Killer leaves Dexter a surprise at the scene of one of Dexter's recent kills, placing him firmly in the cross hairs of his own Homicide Division colleagues.

Dexter and Debra try to dissuade their boss from pursuing a security guard they believe he has wrongly identified as the Ice Truck Killer. Meanwhile, Dexter's girlfriend receives an unwelcome visit from an associate of her imprisoned husband.

The strange suicide of a powerful woman leads Dexter to suspect her shrink of murder, but he gets a shock when a visit to the suspect opens up dark secrets from Dexter's past.
