Mesu wo Karu Mura

A group of female students traveling to a high-altitude astronomy club training camp finds itself stranded after their vehicle suffers a flat tire. A local resident comes to their aid and invites them into his village, but the community harbors a dark tradition: capturing outside women and forcing them into marriages with the villagers. When the students are imprisoned in a storehouse, their teacher risks her life to protect them. However, she is soon dragged into a large hall where the men stand completely naked and aroused. Stripped of her clothing and subjected to relentless physical torment, her endurance finally shatters. Driven to madness by the ordeal, she betrays her students, offering them up to save herself. Meanwhile, the three students left behind in the storehouse face a grim fate. They are stripped of their clothes and bound hand and foot. The villagers take turns subjecting them to systematic conditioning, breaking down each girl physically and mentally until they are entirely subdued and reduced to obedient slaves.
