Mungilal (Anupam Kher) was once a small time Bhai in Mumbai, way back in the 70's. Jignesh (Satish Shah) was his friend cum business advisor. When the law-enforcing authorities turned the heat on the Bhais in Mumbai, the two fled to Bangkok. Now in Bangkok, Mungilal has become a don. An All Asian Bhai Meet is being held in Mumbai. In the discussion, a rival Don of Mungi's, Fursat Lala (Gulshan Grover) proposes an ambitious plan for a piece of land in Alibagh and puts across a valid argument that in their business, it is very important to have a heir. Since Mungi has no one it is decided that Fursat Lala should be made the new Don of Mumbai. However, Mungilal assures the syndicate that he has a heir, who he will present before them in a month's time. However, in his quest to find a heir, Mungilal is caught in a dilemma when four youngsters land up in his house each claiming to be his nephew.
