It's July 2020. Kele and his girlfriend Wen, Xiaokang and Po just graduated, and they want to stay in Nanchang to continue their "dream". Xiaokang got a temporary job; Kele and Wen don't know what to do everyday, and Po only thinks about taking pictures of people and life around him. Later, Xiaokang left, Kele and Wen broke up. Then Wen left. Only Coke and Po stay. At noon, the sun is scorching, and they still can't get out of the zoo.
