 Raisaheb Surajbhan Chaudhary lives a wealthy lifestyle in a palatial mansion with his wife of 30 years, Rajlaxmi, and two sons, Rajkumar, who has been married for several years with Shyama; and Mohankumar who is studying out of town in college. Surajbhan is disappointed with Rajkumar as he has as yet not produced a heir to his family. To make matters worse Mohan, a devout worshiper of Lord Bajrangbali, has taken a vow of celibacy and refuses to get married. Things change dramatically when a young woman named Neena, along with her son, enters the Chaudhary household claiming that Mohan had married her and abandoned her. She goes through a number of tests, including a blood test, which determine that the child is actually a heir of the Chaudhary family. Now Surajbhan and Rajlaxmi want Mohan and Neena to get officially married, though Mohan keeps on objecting that he has never married Neena and the child is not his. Things get complicated when Surajbhan finds out that the child is actually Rajkumar s, and that Neena may have been pulling wool over all their eyes.
