Pulipandi (Vetri) is a loafer who, along with his three sidekicks, will do anything for the sake of money. A shady cop named Madasamy (Kavitha Bharathi) often takes a cut.
The Superintendent of Police is transferred and Benjamin (Aruvi Madhan) an honest officer gets posted. Benjamin is intent on rounding up all the rowdy sheeters including Pulipandi.
Pulipandi and his friends go to Sabarimala to escape the cops. Pulipandi meets Ismail (Hareesh Peradi). Taking pity on him, Pulipandi buys a lottery ticket but he loses it later.
Ismail, who finds the lottery ticket that Pulipandi has lost, gets to know that it has won the bumper prize of ₹10 crore. But he decides to find and give it to Pulipandi.
Bumper is a winner just for the strong and inspiring message it sends. The manner in which the story is narrated is just realistic and therefore absorbing.
Hareesh Peradi, who plays the poor lottery seller with integrity, is just outstanding. Shivani Narayanan has very little to do, but she plays her part to satisfaction.
