Hungover teen Sharon wakes after a wild house party to find a bloody knife and a dead body in the bathroom. But when she pulls on a pair of her late dad鈥檚 'magic' day-of-the-week Y-fronts, she is hurled back in time to the night before the murder. With best mate Sally determined to party at any cost (even her own life), Sharon is trapped in a booze-soaked time loop, desperately trying to stop the killing and uncover the shocking truth before she blacks out.
