When security cameras record footage of a woman being abducted, it isn't long before Captain Donald Cragen and the SVU squad find the woman dead in the basement. Detective John Munch recalls a similar case from twenty years before, sending Detectives Olivia Benson and Eliot Stabler to Sing Sing to speak to the culprit, who begs them to reopen his case and prove his innocence. As strange similarities between the two cases begin to arise, Benson and Stabler face fierce opposition from Ingrid Block, the pit bull attorney for the main suspect who will do whatever it takes to prove her client's innocence. Ultimately, it falls on DA Jack McCoy to decide whether or not the ruthless lengths to which Block went to defend her client constituted a crime itself.
