Law & Order: Special Victims Unit (1999): Ace

When a pregnant woman is raped, Detectives Olivia Benson and Eliot Stabler arrive at the hospital to find that she has fled. Even when someone is arrested for a similar offense, ADA Jo Marlowe says she doesn't have a case in court unless they find the victim and get a statement from her. Soon, Benson and Stabler connect the woman to an illegal adoption operation, forcing them to go undercover and expose the truth.
