In an episode inspired by the capture of the notorious "BTK Killer", the police find a note duct-taped to an abandoned baby containing cryptic clues as to the mother's whereabouts. As SVU detectives Stabler (Christopher Meloni), Benson (Mariska Hargitay), Munch (Richard Belzer) and Tutuola (Ice-T) follow a trail of increasingly ominous (and often gruesome) clues, it is apparent that the mother has been kidnapped--and likely murdered--by a cunning serial killer known as RDK. But in assembling the pieces of this grim puzzle, the detectives arrive at another, even more frightening conclusion: They may be dealing with a copycat killer who intends to surpass RDK with his own murder spree.
