It is the Tamil remake of 'Big'. SJ Suryah is a young man with an immature mind. He falls in love with Simran and gets married to her. The troubles that they encounter form the story.
Exploring into the mind of a youth who is mentally and physically abused in his childhood, the film shows how he slowly turns into a psychopath who kills anyone who comes in the way of the girl for whom he has an obsessive love!
