Vishal (Riaz) and Dr.Vasudevan (Yog Japee) wake up one day to find out that they both are stuck inside a square room devoid of any furniture. The only other element in the room apart from the two of them is the dead body of a man lying in the middle of the room, blood soaked. Vishal and Dr.Vasudevan do not know each other. Soon, Vishal realises that there is a tape recorder near him, he finds a cassette in his pocket, which he plays. The cassette welcomes him to the SQUARE and tells him that his only way of escaping is by finding a clue that only the guy opposite him can see. Soon, Dr.Vasudevan plays the cassette from his pocket and the recording again welcomes him to the SQUARE and tells him that he has been doing a lot of good by saving lives as a Doctor and yet he has committed a grave mistake which he is now getting punished for. He is told that there is only 8 hours remaining for him to escape and his escape would only be by killing the one opposite him.
