Eight people enter a room in a company for an interview for the post of CEO. The room has no windows, the walls are white, and there is a clock attached to one side. There are five men and three women. The men include one smart guy in white, one villain in full black, one coward who always bites his nails, one clairvoyant guy who always laughs like a fool, and one tall guy who wears a mask. The women include one lady in a saree, one in an office skirt suit, and one in jeans and a shirt. The company representative enters the hall and addresses that the former CEO committed suicide in the same room and is roaming as a ghost. The interview is simple: whoever among the eight candidates remains alive and sane after one hour will become the CEO. The timer begins.[3]

The evil guy makes fun of everyone and forces the tall guy to remove the mask, but he refuses. After 10 minutes, the lights suddenly go off. When they are back on, the tall guy is shown being hanged from the roof. They believe that the ghost kills people every 10 minutes, and they must work together to stay alive. The guy who always laughs suddenly begins to laugh hysterically and reveals that he can see ghosts and laughs whenever he sees one. After another 10 mins, the laughing guy is killed with a cut, then the coward dies. People suspect the evil guy, and the smart guy knocks him off. Now, the ladies and smart guy remain.

Suddenly, the tall guy wakes up and reveals that he is a clone of the smart guy and his lookalike. The smart guy kills him with a gun obtained from a hole in the wall. Then, the evil guy becomes conscious and reveals that he is the assistant of the lady in the suit and they have come to the interview together. She orders him to kill the other two ladies. The evil guy kills the girl in jeans, and the smart guy kills the lady in the suit and the evil guy. Now, only the saree lady and the smart guy remain. It is then revealed that they are couples, and he decides to kill himself to make her the CEO, but she stabs herself and dies. Finally, the hero decides to kill himself, but the timer runs out. One hour is over, and the door is opened.

The smart guy is then made to sit in a chair opposite to a man who is a doctor, and it is finally revealed that the smart guy is Ashwin, who is none other than the CEO of the company. He did not die and is instead suffering from multiple personality disorder. The remaining seven characters were his mere imagination. This treatment was done to make him kill all his personalities and cure him. He finally manages to kill them all and is now cured. The company representative who first came at the beginning of the interview comes and talks to Ashwin. He feels happy that Ashwin is safe now and tells him that he had eight personalities. Ashwin is shocked and asks the officer that he had only seven. The officer reveals that he had eight personalities, and the eighth one was that of a doctor. Its then revealed that Ashwin managed to kill only seven characters and the doctor character has taken over him completely, thus making him still suffering from MPD. The movie ends with a laugh from Ashwin.
