视频简介
A group of students who are participating in a university's summer science camp are drawn into an incredible quagmire of conflicts, ranging from the relatively simple conflict between an engaging and forthright young teacher and his older manipulative colleague, to a contest pitting political correctness against free scientific inquiry. Despite the murkiness of some of the issues in the latter conflict, the students pitch in enthusiastically on what they believe to be the side of righteousness, and passions rise to fever pitch. ~ Clarke Fountain, All Movie Guide。一个可爱的妻子、一个听话的儿子、一份稳定的工作－－Dan Vassar觉得自己的生活没有什么不满意的。但是生活偏偏要给他开个玩笑——他竟稀里糊涂成了一名时间旅者，他不仅回到了过去，而且还对他人的生活造成了影响。有些人的生活变得更美好了，但是有些则更糟糕了。在时间旅行的过程中，Dan见到了自己过去的未婚妻Livia Beale－－她曾死于一次神秘的飞机坠毁事故。现在，Dan有了现代知识，他能够挽救她吗？这样做对他自己的未来会有什么影响？他现在所拥有的一切是否也将改变？。
