Liu Da (Qu Chuxiao), Lin Yimu (Ye Zicheng), and Fu Mo (Kong Chuinan) are high school trio best friends. With the end of the college entrance examination, their peaceful lives began to change. On the day when the college entrance examination scores were announced, Liu Da stole his father's car and went around with Lin Yimu to look for Fu Mo who had run away. They met an old man at a barbecue stall and started their respective youth enlightenment, vowing to make their 20s shine among the crowd. Days passed like this, and the three of them just passed their 20s. Even though their lives were completely opposite to their plans and even messed up, they bred new life nutrients and encouraged them to move forward.
