Saleem Bhai Savyasachi is a crime boss in Mumbai who kills the police commissioner with an flintlock gun and sends the gun to Hyderabad to assassinate one of his enemies. Arjun is a struggling actor who orders a hair oil to treat his hair fall, but receives the gun in courier due to mistaken identity and discusses the problem with his friend at night on his terrace. A CI harasses a lone woman at night in their colony. Arjun's friend (who is drunk) couldn't understand the problem, where he accidentally shoots the CI while snatching the gun from Arjun. He tries to report the incident to the police but withdraws after realizing that he shot the CI. He tries to toss away the gun, but fails to do so.

Meanwhile, the hitman who is also named Arjun, receives the hair oil instead of the gun and investigates the matter. Arjun receives another parcel with the photo of Sripati, who is his girlfriend Subbu's father, and is ordered to kill him. Arjun (hitman) finds Arjun's home and holds him at gunpoint while Arjun's parents return from a film and find the gangsters in their house. Arjun convinces them that they are from the shooting crew. The gangsters leave with the courier, but Arjun changes the photo of their target. Sripati acts as he suffers from heart stroke in a bid to leave for US with a reluctant Subbu. The gangsters realize their mistake but decide to help Arjun. They inform him that Saleem Bhai hired another assassin to kill Sripati.

Arjun and his family along with Subbu's father leave for a temple shrine where after secretly defeating the goons, Arjun finds the assassin to be CI and saves Sripati from him. Subbu's mother then reveals to everyone that Sripati dreamt of becoming an actor and finally landed a lead role in Saleem Bhai's biopic. Sripati's car broke down on the first day of filming and he travelled with the police commissioner. The police commissioner attacked Saleem Bhai, who swore vengeance on Sripati. After narrating the events, Sripati then boards a train to Mumbai and Arjun tries to convince him to return. They later realize that it is a shooting spot and the train isn't going anywhere. Saleem Bhai attacks Arjun and Sripati at the railway station, but they defeat him. Impressed with their performance, the producer of the film offers them roles in his film where Arjun and Sripati finally become actors.
