Nimmi (Tabu) is Abba Ji's mistress, but she and Maqbool are secretly in love. Nimmi encourages Maqbool's ambitions and persuades him to kill Abba Ji to take over as Don. Maqbool is torn between his love for Nimmi and his loyalty to Abba Ji, but he begins to prepare the ground for becoming a Don, by ensuring that others in the line of succession cannot interfere. Finally, Maqbool murders Abba Ji in cold blood while he is in bed at night, with Nimmi next to him. Maqbool gets away with the murder and takes over as Don, just as planned; but both he and Nimmi are haunted by guilt, seeing Abba Ji's ghost and unable to wash the blood from their hands. There is also suspicion, within the gang, of Maqbool's role in the death of Abba Ji, and eventually the lovers meet a tragic end.
