A mental patient with a heart problem, Xu Lian, escapes from her facility to take back her daughter, Xiao Ai, from her grandparents' home. Her grandparents attempt to take Xiao Ai elsewhere, but their car crashes with Xiao Ai as the only survivor. Xu Lian decides to move to her grandfather's villa in a remote countryside with Xiao Ai. Xu Lian begins to experience haunting since the first night she moved in, including a girl with a charred face, which she suspects comes from the girl's painting in the staircase wall. Xiao Ai, meanwhile, discovers a tricycle that belongs to "Xiao Ai", apparently the name of the charred girl. Everyone in the village also seem to know Xu Lian to some degree, including a mentally handicapped man who claims to be searching for his wife and daughter.
