The Exorcism of Molly Hartley

Molly Hartley has grown up, but the demon still lives inside her. The girl learns that, according to a secret agreement, her soul belongs to the devil. Six years after graduating from high school, she is accused of murder and sent to a mental hospital, where she uses her power to harm patients and staff. Her only hope is an exorcism, which can be performed by a defrocked priest who wants to save Molly.
