Sergeant Hank Voight and Detectives Erin Lindsay and Jay Halstead track a child pornography victim to his last-known whereabouts in New York City, where Sergeant Benson and the SVU squad get a new lead - evidence of a livestreamed pornography "club" that caters to its subscriber's shocking requests. When Lindsay discovers someone from her past is involved, she hopes it will help lead them to the site's ringleader, but tensions between Voight and Benson could threaten the case.
