From the director of Friday the 13th and The Texas Chainsaw Massacre comes new Horror. During an all-night, drug-fuelled party at an abandoned asylum known for the horrific treatment of its patients, a group of ordinary teens decide to experiment with the occult, mysteriously leading to a violent possession. In an effort to find help, the group rushes to escape, only to find themselves locked inside with no means of communication. In an attempt to save their friend possessed by the demon, the amateurs try to perform an exorcism. Instead of solving the problem, they unleash an even more powerful and vengeful spirit, one with a distinct motive and which wants them all dead. What started as a harmless paranormal experiment turns into a fast paced bloody paranormal nightmare.
