This offbeat action drama revolves around Murugan (Vikram) a fit and active man, who dreams of becoming a successful villain in films. In order to fulfill his dream, he works very hard on building his body up to look strong and powerful. He lives with a group of friends who spend most of their time at the gymnasium.
In a fateful twist, he accidentally meets an elderly man Dakshinamoorthy (K. Vishwanath) who is under pressure from his son Chidambaram (Avinash) to sell his orphanage, to a scheming politician Ranganayaki (Sana) who is a major player in a land grabbing racket, along with her hatchet man 'Vaappa' Abdul Kadhir (Pradeep Rawat). Murugan eventually falls in love with Dharshini (Deeksha Seth).
The mighty Murugan transforms into a one-man army and becomes Dakshinamoorthy’s saviour as Ranganayaki and her men begin targeting them. Will Murugan be successful in demolishing Ranganayaki's powerful network against all odds? Can he expose Ranganayaki's true colours to the world and bring her to justice?
