Busse, Rayna and Lex are on patrol and see a boat. There is a fancy party going on. They all wear Venetian masks. Marga has a date and they dine in a restaurant. While they're eating the party from the boat come in. Somehow Marga is interested in them and follows them for a while. The party leaves and go back with the boat. When they arrive back, the captain of the boat walks to the after deck and finds four of the party bent over the body of the woman in a red dress. Ryan was murdered with a pin straight through her heart. When the four are questioned they exactly tell the police how Ryan was killed with the pin. Nora is not satisfied with this explanation. She wants to know who of the four killed Ryan.
