S10, E14: When a man is found badly beaten with no memory of what happened in a strip club parking lot, Detectives Olivia Benson (Mariska Hargitay) and Elliot Stabler (Christopher Meloni) are at a loss for evidence as a rainstorm washed away any clues. A fake fingernail embedded in the victim's back leads the detectives to believe that the attacker is female. Detective Benson and Stabler turn to the female dancers at the club for questioning, but a homeless man, Sid Gabbert (guest star Paul Lazar), points the detectives to the victims truck. Using evidence found in the truck, the detectives learn that the victim, Mark Van Kuren (guest star Frank Grillo), was sent to repossess the car of strip club dancer, Molly Misty Lambert (guest star Heidi Marnhout). After questioning Misty, Van Kuren awakes in the hospital with no memory, but brings the attention to his ex-wife Ellen (guest star Wendy Makkena) and their 13-year-old transgender son Henry (guest star Bridger Zadina). Also starring: Richard Belzer (Detective John Munch), Dann Florek (Captain Donald Cragen), Ice-T (Detective Odafin Tutuola), Michaela McManus (A.D.A Kim Greylek), Tamara Tunie (Dr. Melinda Warner), and B.D. Wong (Dr. George Huang).
