Lee Ji-Bong is a former Olympics bronze medalist for weight-lifting, but a career-ending injury from the games forces him into early retirement. Unable to find another vocation, he becomes destitute. Down and out, he ends up working at a shady nightclub passing out flyers until he is visited by his former coach who insists he begin a career as a coach at a high school. There, he forms a weight-lifting team comprised of a rag-tag group of outcasts.
In June 1950, soon after the start of the Korean War, a troop of North Korean soldiers enter a small South Korean village. Captain Jeong-woong proclaims that they came to liberate the villagers but their true agenda is to ferret out the reactionaries. The villagers and Seol-hee, who is separated from her fiance on her wedding day, offer them heartfelt hospitality and cooperation to avoid falling out of the army's favor. Eventually friendships starts to build up between the soldiers and the villagers.
