As the group arrive and the party starts, Brandon and his friend Cal (Austin Basis) show everyone around, revealing that the house is filled with cameras which can be monitored on screens in the monitoring room, due to the house previously being used as a reality show set. After a few hours of partying, Marcus suggests a game of Seventy Five. Various people take part, until one caller murders someone for the group to hear. They all decide to not answer the phone and continue with their night. As the party finishes and most people leave, Karina and Brandon reconcile. Becky (Ellen Woglom) and Julie (Soraya Kelley) stay up partying with two boys. However, the killer soon arrives at the house and decapitates Becky, before killing the boys and Julie. The killer proceeds to decapitate a boy in the hot tub before drowning his girlfriend. Kareem witnesses the murders and rounds up Roxy, Marcus and Anna (Denyce Lawton) to leave.
