Six mature women gathered at a certain hot spring inn for a "girls' get-together." Reuniting as former friends and acquaintances, they leave their daily lives behind to surrender themselves to the healing powers of the hot springs. However, amidst the steam, on the tatami mats, in the evening corridors, and in the open-air baths, their uncontrollable passion sparks. Encounters with men appearing as inn employees and regular guests awaken even further stimulation. Finally, a breathtaking orgy ensues in the open-air bath where everyone gathers!
