In 1974 Cleveland, the kids Wendy, Judy, Kelly, and Nick are playing hide-and-seek in a derelict building. While going to school, siblings Kim, Alex, and Robin stop near the building since Kim needs to return home. Robin flees from Alex and runs to the building, and the quartet frightens her and she falls off the window, immediately dying. They promise to each other to keep secret about what have just happened to Robin. Six years later, on the prom night, serial killer Leonard Murch, who is suspected of murdering Robin, escapes from the mental institution where he is interned and the police is afraid that he returns to town to seek revenge. When Murch is captured by the police in another town, Lt. McBride feels relieved and resolve to enjoy the prom. However, a killer is beginning a crime spree in Hamilton High School.—Claudio Carvalho, Rio de Janeiro, Brazil
