A young man finds that his girlfriend Larissa Welsh (Taryn Manning) has been attacked in her apartment with evidence that points to her buried past. Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) go in search of her attacker and discover that an elderly man, Orville Underwood (guest star David Patrick Kelly), may have been involved in traumatic events of Welsh’s past. For the detectives, solving the case comes down to who was in possession of the evidence.
