A group of female students are on their way to a training camp in the highlands for the astronomy club.
When their car gets a flat tire and they are stranded, they are rescued by a local and invited into the village.
However, in reality, the village has a tradition of capturing women from outside and making them villagers' wives.
A beautiful teacher puts herself on the line to protect the students who have been raped in the storehouse, but when she is taken to the large hall, she finds the men stark naked and erect.
With their clothes torn off and tortured endlessly on the spot, their bodies reach their limits.
The teacher, having lost his mind, offers up the students as substitutes.
Meanwhile, the three students who are left behind in the storehouse have their clothes stripped off and their hands and feet are bound.
One by one, their bodies are raped by the villagers, and they are broken both physically and mentally, becoming like human toilets.
