The girls in the astronomy club were going on a trip. They were excited to stay at a mountain lodge. On the way, their car got a flat tire. They were stuck.
Some friendly locals offered to help. They thought they were lucky. But the locals took them to a hidden village. The village had a terrible secret. For hundreds of years, they trapped women from outside. These women were forced to become brides for the village men.
The girls were locked in a dark, cold storage building. Their teacher tried to protect them. She went with the villagers to talk. But in the main hall, many naked men were waiting. They attacked her. It was a terrible and continuous assault. It broke her mind.
To make it stop, she did the unthinkable. She told the men where to find her students.
