Retired soldier Yang Qing is struggling to raise his son. His fourth-grade boy, Yang Xiaoyang, is hooked on video games and at the bottom of his class. After every attempt at discipline fails, this grassroots community worker makes a startling decision: every night, he takes his son out on an electric scooter to deliver food through the city’s streets and alleys. They’re doing more than delivering meals. They’re embarking on a journey to mend their father-son relationship, and behind every order, they encounter the warmth and rough edges of the city.
