Radha, seeking revenge, infiltrates Billa's gang. After several unsuccessful attempts at nabbing Billa, the police finally succeed, but Billa dies during the pursuit, botching DSP Alexander's plan to reach the source of all crime—the man Billa reported to—by capturing Billa alive. Alexander buries Billa's body, ensuring that people believe that he is still alive. Alexander remembers his chance encounter with Rajappa, a simpleton trying to support two small foster children, who is a doppelgänger of Billa. Alexander hatches a plan to transform Rajappa into Billa and place him back into the crime nexus, but this time as a police informer.
