During the summer vacation, seven-year-old Ningning was sent back to the countryside to be taken care of by his grandfather Li Fuchang, who was over 70 years old. Li Fuchang accidentally got the contact information of an old friend who had a stroke and was dying. He decided to take his grandson and ride a motorcycle tricycle to visit his old friend thousands of miles away. The film uses "crossing Zhaoguan" to refer to life, and is a rare Chinese rural road movie.
