Sam lives by her "try anything once" motto to a fault. On an otherwise normal night out, she takes an experimental drug from a stranger at the bar that lets her see into alternate timelines. When she witnesses her own murder in a parallel world, she realizes that the mysterious series of hit-and-runs plaguing her college town are anything but accidents. Sam and her friends decide to stop the killer once and for all, but time travel has unforeseen costs, and one of them will have to pay.
