Sixteen year-old Avery Capshaw's parents report her kidnapped, and the SVU finds signs of a party turned violent. Her boyfriend, Manny Montero, is a scholarship student from the Projects, and though his family swears he's on the right track, Amaro suspects he's involved with a dangerous gang. When Manny refuses to talk, the cops are forced to arrest him, but the violence only escalates. Meanwhile, Benson is sworn in as the SVU's new sergeant.
