After a string of miraculous events, Yugo Kochi, Fuga Onishi, and Masato Takemura complete the bingo on the very first day. But determined to become the first team in the show's history to achieve four bingos, the three split up to tackle separate missions.
Fuga heads off in search of the mysterious "Earth Sauna," despite having little idea what it actually is. The destination turns out to be a snow-covered mountain, where he takes on a mission truly worthy of the name Wild Tripper.
Meanwhile, Kochi and Takemura travel to Furano in search of the "center of Hokkaido." Having never successfully hitchhiked on his own before, Takemura takes on the challenge under Kochi's guidance. However, an unexpected turn of events pushes him to the brink of an emotional breakdown.
