Two children in rural China navigate punishing daily commutes to reach a classroom. Yang Jiaojiao, eleven, lives with her family high on the Tibetan-Qinghai plateau in Mao County, Sichuan, where the school run means picking a path down steep mountain terrain with no room for error. The film then follows Lu Tiansen, thirteen, who grows up on Chang Yao Island in Fujian's Xiapu County, catching crabs and swimming with friends on weekends while his father spends backbreaking hours harvesting seaweed for a living. Tiansen's route to school depends on the tides and the sea itself, and his father's hope for a better future rests on him getting there. Camera crews follow both families through their villages, homes, and the physical hazards of the journey itself, letting the landscapes, the labor, and the children's own routines carry the story. The episode is part of a series documenting how kids around the world reach school under conditions most viewers will never have to consider.
