Kaun

A young woman (Urmila Matondkar), home alone, is watching the news of a serial killer on television when the doorbell rings. The woman sees through the peephole that it is a young man, who later identifies himself as Sameer A. Purnavale (Manoj Bajpai), claiming to be a business partner of Mr. Malhotra. She is reluctant to open the door, due to the news broadcast of a killer on the loose. The woman claims that the house doesn't belong to Mr. Malhotra but to Mr. Gupta. However the man believing that there has been a mix up, persistently keeps ringing the doorbell even after the woman tells him that she won't let him in.
