退役軍人Devine每天搭乘6:20的火車前往市區的金融公司上班，擔任分析師的他希望有朝一日也能名利雙收，一天他卻收到一封奇怪的訊息「她死了」，接著警方通知他，前女友在他的辦公室上吊自殺，而一通神秘的電話則警告他，若不想讓過去在軍中的事情曝光，就要接受委託，深入調查公司背後的金融秘辛… Having survived combat tours in Afghanistan and Iraq and been decorated with medals, Travis Devine mysteriously leaves the Army under a cloud of suspicion.

But it is on this daily journey that he passes a house where he sees something that sounds alarm signals he cannot ignore.
