In a simple apartment in an unnamed city, two sisters are living together. The younger sister, Ping, is struggling with a severe eating disorder. She came to stay with her older sister, Ming, with the hope to save her out of the mental illness that is drowning her life. It becomes clear that Ming, who has been playing the role of rescuer with a strong and resolved appearance, is actually struggling with her own emotional turmoil. Out of despair, Ping goes to join a support group, which turns out to be a pro-anorexia cult. Ping is pushed to the edge of death.
