Together with the previous two seasons aired in 2022 and 2023, respectively, it documents how Salopek's cross-country trek in China began in September 2021 in Yunnan's Tengchong and concluded this May in Dalian. The documentary series has won a considerable following worldwide.

When Salopek arrived in China, he had already been walking for eight years on a quest to retrace the migration path of early humans by traversing four continents in more than a decade. The giant project commenced in Ethiopia in 2013 and is scheduled to end in Tierra del Fuego in South America. His China expedition is a part of this project.
