At the foot of Tianya Mountain lives about 180 households, rumored to be descendants of the Yang family generals. Villager Yang Eryou, influenced by his father, is skilled in the Yang family wrestling techniques. During the temple fair this year, Guokui Yang was severely injured by the Japanese devils, forcing Yang Eryou to take on the family's burdens and sell Guokui in the town. When he was wrongfully accused of being a fugitive by the security team, he was saved by the famous actress Shisan Hong from a theater troupe while escaping, and they slowly fell in love. Afterwards, Eryou took over his father's role of delivering information, medicines, and salt to the guerrilla fighters on Tianya Mountain. In particular, Eryou was praised by Captain Wang for cleverly hiding information in the Guokui. Locals love wrestling, but the Japanese devils, under the guise of hosting a wrestling championship, brought in judo experts from Japan, attempting to psychologically conquer the local population. Chinese wrestlers faced continuous defeats, and Yang Eryou was forced to step in and secure a victory. Enraged, the Japanese invaders sought to capture Yang Eryou, who escaped the ancient town with the help of Shisan Hong and others. The Japanese pursued him all the way to Tianya Mountain, where the guerrilla fighters were based, leading to an inevitable great battle. Shisan Hong and others heroically sacrificed themselves, while the Japanese invaders suffered heavy casualties from the guerrilla ambush.
