Hero launched Jackie in the big league. Hero is the story of a criminal transforming and evolving as a good person under the influence of love. Jackie is a baddie with a heart of gold though, who has to settle scores with the area's 'Thakur' and his police officer son Sanjeev Kumar. So he opts for kidnapping their soft spot, Radha, Thakur khandaan's only daughter. The music of the film became superhit. Meenakshi Seshadri had a second coming with Hero. Her debut film Painter Babu under the baton of Manoj Kumar was a flop. Radha is given to understand that Jackie and his gang are police people who have taken her away to the safety of jungles because their house has been invaded by dacoits.
