Teenager Elena Peters and her friends, Missy and Josh, go to a party. Elena witnesses her boyfriend, Brian, with another woman. She leaves the dance floor and enters an isolated room. There, she discovers a red trunk and opens it to find a severely injured Arkin O'Brien. Arkin grabs Elena and they dodge a steel spear, which triggers a series of deadly traps that kill everyone on the dance floor. The Collector appears and kidnaps Elena, while Arkin escapes by jumping out of a window, landing on a car and breaking his arm in the process.
