Sandeep, a bachelor, lives a fairly wealthy lifestyle along with his mother and a servant, Sevak, who has grown up with him. He decides to travel to Shikarpur to close a business deal and takes Sevak along with him. Although the duo have never been to this region, everyone appears to know them very well. Unable to get anyone to clarify how they are known to them, they decide to complete their business and return home. Little do they know that their departure will be substantially delayed when two women show up claiming to be Sandeep's wife and sister-in-law.
