An explanation of sorts is provided. He’s on a mission to unmask as terrorist plot. The train was blown up this morning, a few hours ago. The same terrorist is believed to have planted a much larger bomb somewhere it downtown Chicago.
Some sort of quantum-computer device called “The Source Code” can send Colter’s consciousness back in time to relive the last 8 minutes of Sean’s life. This will take place in some sort of temporary pocket quantum universe. He can change Sean’s actions but nothing he does can change the fact that the train has already been blown up in the real world.
However if he can find the identity of the bomber before the second bomb goes off in the real world then the second explosion can be prevented, saving vast numbers of people.
So back Colter goes, again and again and again, failing each time, under increasing pressure as the clock ticks away, and under increasing mental strain as he gets to know the people who are about to die.
I wasn’t very impressed by the trailer, but I was impressed by the actual movie. It is probably better than it sounds, well acted and well-thought-out. Everything fits together in the end. Well, almost everything.Show ▼
