When two sisters are killed in a fire, Detectives Olivia Benson and Eliot Stabler are confused about why they are called to investigate. They soon discover that Stabler's old partner, ADA Jo Marlowe , has been put on the case -- despite the absence of a sex crime -- because the two victims were so young, and that she has enlisted the duo to help. However, as the investigation continues, Benson and Stabler find that the case might be more suited to their department than anyone originally assumed, and Stabler's interrogation tactics threaten to get the detectives into trouble.
