On a rainy night, Arun helps a woman reach home safely. In return, she lends him her car and asks to give it back the next day. However, the next morning, Arun finds her dead, locked up in the boot of her car. While he insists on going to the police, Somu (Prasanna), his new roommate, warns him of the consequences, and the two scramble to find evidence and get rid of the body.
As and when they try to cover up their tracks, they keep making one more mistake, leaving behind a new clue. Apart from adding value to the story, what this does is make way for several amusing subplots. For instance, when Arun and Somu try to throw the body from a bridge, the director gives it a Panchathantiram-esque treatment, leaving audiences in splits.
That said, the film does very little to steer clear of predictability. In addition, the film lets us in on a crucial motive early on in the film, even if the characters learn of it only towards the end. This chips away at the genre’s edge-of-the-seat effect. Almost making up for it, the makers load the pre-climactic sequence with several twists, but it comes off as overloaded.
