In order to avoid a ghostly figure in the road, high-school senior Brent Mitchell (Xavier Samuel) wraps his car around a tree, killing his father. Constantly confronted by his mother's emotional collapse after the accident, Brent escapes into a marijuana-fuelled world of loud metal music to block the pain and guilt. Dejected and out of sorts, he has a shot at happiness with his girlfriend Holly (Victoria Thaine), a grounded, caring girl with drop-dead good looks—a dream date for the high school prom.
But his plans are thwarted by a disturbing series of events that take place under a mirrored disco ball, involving pink satin, glitter, syringes, nails, power drills and a secret admirer. Brent has become the prom king at a macabre, sadistic event where he is the entertainment.
