Four youngsters from different fields (nurse, journalist, mechanic and a computer engineer) decided to create a group to punish those who make the system dirty. As it is India, their aggressive acts got a good support from the public who were also furious. The politicians wanted to see an end to this and the commissioner of police gives the responsibility of the case to ACP Ashok Kale. The cat and mouse game between the cops and the Ungli gang, the activities of the gang and how it all ends on a positive knot is what this film talking about.
