On their first wedding anniversary, Lucky Singh, an entrepreneur from Punjab walks into the lives of Anil Chandra and Bhamini. Little do they know that this man will change their future

Murugan has a rivalry towards tigers from childhood. From childhood he gets trained to hunt tigers,which are danger to villagers. Now he is Pulimurugan, but he has to face the tigers as well as the dangerous humans, as he is forced to move out of forest. This forms the rest of the story.

The film revolves around Madhavan Nair (Nedumudi Venu), who unknowingly kills a teenager, and his eldest son Raja takes the blame and is sentenced to jail for five years. After returning from jail, his father refuses to accept him still with no knowledge that his son was innocent, and so Raja moves to Madurai and there he rescues the life of the son of Maniannan (Charan Raj), the village landlord, and then Raja turns his right hand and is named as Madurai Raja. Years later, he started being known as Pokkiri Raja (Mammootty).
Meanwhile, Surya (Pritviraj), Madhavan Nair’s younger son, is a young, energetic, educated, naughty guy who is well-famous for his rowdyism in his village. He is sent to Ernakulam to his brother-in-law Sugunan (Suraj Venjaramoodu) to change his character, who is a scary cat. At Ernakulam, Surya falls in love with Aswathy (Shriya Saran), unknowing that she is the daughter of Rajendra Babu (Siddique), the City Police Commissioner. Sugunan takes advantage of Surya’s character and sends him in his uniform to take care of some severe police cases. Surya gets arrested for this offence. Rajendra Babu finds that Surya is in love with his daughter and charges Surya with another drugs case and makes it a non-bailable offence. Meanwhile, Rajendra Babu plans to murder Surya in jail, and he gives the contract to Pokkiri Raja. At this point, Madhavan Nair goes to Madurai in search of his elder son who left for Madurai 10 years back, and asks for his help to rescue his younger son Surya. After realising that Surya is his brother, Raja starts the game to help his family and end Rajendra Babu.

When an illegal hooch baron’s reign of terror troubles an entire village, the people turn to the only man who can save them: Raja, the flamboyant don with a heart of gold.
