If you haven't seen the preview for the yet. Its about a soldier who is implanted in what they call, "Source Code". His mission is to find out who planted the bomb on a train. He gets only 8 mins each time and has several chances. The goal is to identify the bomber so they can stop a larger attack later. The movie was very entertaining. I recommend it to all, but make sure you pay attention the whole time cuz you could get lost.
