Debra's discovery of an Ice Truck Killer victim being found alive gives LaGuerta and her Homicide detectives their first chance to identify the notorious serial killer. Debra and Doakes, assigned to the case, sit with the mutilated victim, in the hopes that he will be able to identify the killer. While Dexter works on the case, Rita tells Dexter about a friend of hers whose fiance has disappeared while immigrating from Cuba by way of a coyote (a human trafficker). When the fiance turns up dead, Dexter decides to hunt down the murderous coyote. But things don't go as planned when Dexter realizes that there is more to the vicious trafficker than his careful stalking prepared him for.
