Mu Qing Sanatorium, on the surface, is an urban pure land for healing mental trauma, but behind the scenes, it is a nest of alienation buried deep underground.
Zhong Wan, a senior student in the Department of Journalism, entered this strange prison because his friend behaved abnormally after being discharged from the hospital.
Here, she met four sober patients: the cold and restrained Qin Baiyun, the hard-spoken and soft-hearted Jiang Yi, and the always nervous Jenny, as well as an eccentric hearing-impaired little girl Su Ruiman.
As the team goes deeper underground, those so-called "mental illnesses" are just bait for parasitic monsters. When brain-eating maggots eat away at consciousness, and when trust is on the verge of being broken, they must use flesh and blood as a shield to reveal the truth and complete redemption.
Purpose: To explore the mental pressure and human trauma in modern society, through the survival adventure of a group of marginalized people, to show the warmth and self-salvation of group portraits in a dark environment, and to explore the fragility and brilliance of human nature under the appearance of monsters.
