Six mature women gathered at a certain hot spring inn for a "girls' night out." Reunited as former friends and acquaintances, the girls leave their daily lives and surrender to the healing power of the hot springs. However, in the steam, on the tatami mats, in the hallway in the evening, and in the open-air bath, their irrepressible passion sparks. Encounters with the men who appear as employees and regular customers of the inn evoke further stimulation. And an amazing orgy in the open-air bath where everyone gathers!
