On his way to Dinapur, the dacoit's hideout, he meets a grievously injured cop, Inspector D'Souza, (Satyen Kappu) who dies protecting his stash of ammunition from local dacoits. Inspector D'Souza was en route to the village of Dinapur to set up a police station with his men and the ammo, and he leaves the weapons at Ajit Singh's disposal before succumbing to his wounds. Ajit Singh uses this new found stash of machine guns and grenades to pose as a cop and sets up a police station in the aforementioned village with the help of the villagers. 
Ajit's love interest is the feisty and pretty village belle Radha (Hema Malini), who is the niece of dreaded dacoit Bharat Thakur but hates his ways and supports Ajit Singh.
