The movie is about a submissive pushover Karthik
Life changes completely and the new Karthik seems invincible. The twist comes when he has to admit that he receives calls from himself to Shonali (Deepika), the lady love. Despite being warned against it by KOP, RLK commits the blunder. An angry KOP is now determined to 'finish' RLK. And thus begins the nose dive for the latter.
What happens to RLK, thereafter? Who is KOP? That's the story.
The treatment for a serious subject like Schizophrenia, I must say, is shallow. But that doesn't mean the movie is bad. The trademark muted performance of Farhan Akhtar and pretty Deepika keep your eyes glued. Though I felt the chemistry was lacking between the two. The movie is certainly not for the masses. Though it is not gripping, it certainly doesn't bore you.
