Mungilal was once a small time Bhai in Mumbai, way back in the 70's. Jignesh 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 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 an 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 an heir, who he will present before them in a month's time. Fortunately, Mungi and Jignesh find a letter of Mungi's estranged sister Angoori. The letter reveals that Angoori gave birth to Kamal, who looks exactly like Mungi. Mungi is thrilled and resolves to hunt for his nephew in Mumbai where he comes across Johnny English, a detective, who promises him to find Kamal in 20 days. In return, Mungi promises to pay 50 lacs to him.
