This is specially a science fiction movie about parallel time travel. The story line is based on parallel time line travel a man who have already died the scientist sent his sense to another person by parallel time line concept. It is very hard to explain the story line as it is very complex thought.
I have seen this movie twice and enjoy it each and every minute. This is a really very excellent movie. what a thought. So if you do not see this movie yet go for it and sit tight and enjoy it.
