Chen Chaoseng, a food delivery rider, returns to his hometown for his grandfather's funeral. His grandfather leaves him a drumstick and a wooden token, entrusting him with protecting the village's century-old dragon boat. Hidden beneath the boat is an emergency fund preserved by overseas Chinese clansmen, which can only be found with the boat's guardian token and the skill of reading the tides and discerning the currents. Investor Zhao Jinhai uses cultural tourism development as a pretext to covet a sunken container at the bottom of the river, win over villagers, and seize collective assets for himself. Chen Chaoseng rallies the villagers to form a dragon boat team and trains them rigorously. During the Dragon Boat Festival, a sudden river emergency strikes. His misguided older male cousin comes to his senses and joins him in the fight. The entire village unites to tame the tide with two dragon boats and avert disaster. The conspirators' schemes are exposed and dealt with according to law, and the property is returned to collective ownership. Chen Chaoseng puts down roots in his homeland, carrying on dragon boat racing, Yingge dancing, and Chaoshan folk traditions while safeguarding the bonds and values of his native community.
