一场科学实验中发生的意外让时间发生了反弹,导致人们只能生活在4月27日这一天,重复的日期,重复的景色,重复的生活,讽刺的是,深陷时间漩涡里的人们并不自知。在这些人之中,巴瑞(乔纳森·斯沃曼 Jonathan Silverman 饰)是一个例外,周遭世界发生的荒唐变化,被 他悉数看在眼里,然而,这份清醒带给他的却只有痛苦,因为在这一天,他的同事丽萨(海伦·斯雷特 Helen Slater 饰)惨遭谋杀。 悲伤之中,巴瑞决定利用凝滞的时间找到杀害丽萨的凶手并挽救她的生命,殊不知,改变命运并非易事。经历了一次又一次的失败,眼见着丽萨一次又一次的离开自己,巴瑞并没有绝望,因为他知道,他的唯一不缺的,正是时间。Barry Thomas is the average office worker. He becomes attracted to Lisa Fredericks who works in the same company. After work, Barry witnesses the murder of Lisa and goes to a bar to get drunk. Later that night, there is a storm and Barry gets a shock from a lamp's faulty power wire at exactly 12:01 am. The next morning, he realizes that everything is happening exactly as it did the previous day. The next morning the day is repeated again. It is now Barry's job--being the only person alive who is aware of this time loop--to stop the murder of Lisa, and stop the time loop or be caught in time forever.
