For three friends, the most magical night of high school becomes a terrifying fight for survival in this chilling horror-thriller. Donna Keppel, played by Brittany Snow, is still haunted by the brutal murder of her family years ago, a tragedy she narrowly escaped. As she, along with her boyfriend Scott Porter and their close friends, finally looks forward to the joy and romance of their senior prom, a dark shadow from the past reemerges. The man responsible for her family’s death, a dangerously obsessed former teacher portrayed by Johnathon Schaech, has escaped from custody and is determined to finish what he started, with Donna as his ultimate prize. Under the direction of Nelson McCormick, the opulent hotel hosting the prom transforms from a glittering sanctuary into a claustrophobic maze of terror. With her friends Brianne Davis, Dana Davis, and Jessica Troup caught in the killer’s path, and her uncle, Detective Winn, Idris Elba, desperately searching for her, Donna must confront her deepest fears. The night descends into a deadly game of cat and mouse, where every darkened corridor and empty ballroom could be hiding a predator, proving that some nightmares are relentless enough to crash the party.
