Army Captain Colter Stevens finds himself working on a special program where his consciousness can be inserted into another human being. The only catch is can only be there for 8 minutes at any given time. That morning, a bomb exploded on a commuter train just outside Chicago. He occupies the body of teacher going to work on that train and is confused as to what he is doing or why he is there as his last memory is of flying his helicopter on a combat mission in Afghanistan. Those in charge of the program explain to him that there is a bomb on the train that must locate it. More importantly, he must identify the bomber as another bombing is expected later that day. He is also told however that he cannot change the past and can only gather information. As he develops a liking for his traveling companion Christina, he sets out to test that theory.
一句话评论：影片情节再现，难点解释（全剧剧透，渗入！）。对电影最后数分钟以及源代码系统的理解。不懂结局的来看。《源代码》：《月球》上的“似曾相识”。不仅仅是个8分钟直到型循环 | It's gonna be OK.。《源代码》告诉我们的三件事。用四句话讲明白狗血剧情，小心被雷到。给中国科幻电影指条明路——《源代码》的省钱之道(技术贴！)。细思恐极。如果一切停止在那一吻。
