This story is about a young man named Sam Reed, who has inherited the power of "The Butterfly Effect" and attempts to solve the death of his girlfriend using his ability, only to unwittingly unleash a case of a vicious serial killer. With his ability, he can "travel" back in past times to see murderer cases, to analyze them, and even to "fix" them. Too bad, every times he travels back in time, to "fix" cases, things change in the future.
It is all started when there was a fatal fire in his childhood, that somehow given Sam the ability to travel back in time, so he used his "psychic" talent to help fight crime. In order to save an innocent man, Sam has to travel back to try and track who is the serial killer. Unfortunately, what he did just make things getting worse. For every things he did in the past, makes he become the suspect in the future. I like this movie, because it makes me curious about who is the real killer. The story line is very good. This is another mystery movie you should see.
