Office ladies Ko Asumi and Sumi Kurokawa work at a real estate company in Tokyo. The two headed into the mountains to scout a location for a company outdoor event. However, they got lost on the unfamiliar mountain trail and fell far behind schedule. Eventually, searching for a place to stay overnight, they came across a mountain lodge about to go out of business. The owner, Kitahara, was already finishing up his final cleanup and refused their desperate pleas for shelter. At that moment, Kitahara's friend Kudo arrived, took pity on the exhausted women, and opened the door to unexpected developments.
