Dhanush plays Prabhu, an unemployed graduate who convinces his father to buy him a Suzuki Shogun bike using the father’s retirement fund. The bike becomes his lifeline—he uses it for courier services, wins the heart of his lover Hema (played by Divya Spandana), and gains respect among his peers. Trouble begins when his friend borrows the bike and it gets stolen. Prabhu’s quest to recover the bike leads him into the crosshairs of a sadistic gangster named Muthu (played with terrifying intensity by Kishore Kumar G.).
