In the hustle and bustle of Beicheng, ordinary young man Chen Mo and his friends around him face realistic pressures and ideals. After many career failures and emotional ups and downs, Chen Mo met new partners by chance. During the ups and downs of entrepreneurship, love, and family, he was constantly lost, awakened, and transformed. In the past few years, everyone has shared the joys and sorrows, and gradually grown up amidst the setbacks of life - some have realized their dreams, and some have left regretfully, but the friendship and emotion between them have become the fulcrum for them to stand firm in the city. In the end, Chen Mo realized the meaning of watching youth in the big city when an autobiographical film was released.
