Sister Drum

The female lead volunteers to teach in a mountain village, where a little girl tells her she is the A Jie Gu. Every night, she hears strange sounds while trying to sleep and is terrified. Auntie Ge from the village takes her to buy sleeping pills, but they barely work. That night, the female lead hears someone crying. She goes to investigate and discovers a woman locked up in Auntie Ge's house. Realizing the villagers want to harm her, she pretends nothing is wrong and plans her escape. She uses the villagers' belief that menstruation is unlucky to get away, taking the abused woman with her.
