Moju, an elderly man living in a fishing village in Bangladesh, devotes himself to physical training even today. Boli, a traditional sport in Bangladesh, is a type of wrestling, and Moju declares war on Dopor, the Boli champion who lives in the village. The villagers laugh at Moju, saying he is crazy, and Moju's son, Shafu, tries to lock him up and prevent him from competing, but there is no way to avoid a match between Moju and Dopor.
