SVU joins Chicago P.D. in a manhunt for two notorious escaped serial killers.

The crossover starts on Law & Order: Special Victims Unit S17E14 Nationwide Manhunt (I).

While out on a bank run for his off-duty security job at the dispensary, Halstead and his co-workers find themselves under attack by a violent robbery crew. Meanwhile Roman, Burgess, Antonio, Halstead, Ruzek and Atwater follow-up on a lead and track down a potential suspect.

Burgess gives chase after Roman is wounded by a hooded perp who opened fire on their patrol car and shoots who she thinks is the suspect, but no gun is found at the scene—and the person she shot is a 17-year-old honor student.

Intelligence investigates when a young man is beaten and his fiancée is apparently abducted. Lindsay surprises Halsted with a big question. Cdr. Fogel takes Platt to task for going over his head to have Tay assigned to District 21.
