Exeter

At an abandoned asylum known for its history of horrific patient treatment, a group of ordinary teenagers gathers for an all-night, drug-fueled party. During the event, they experiment with the occult, which mysteriously leads to a violent possession. Attempting to seek help, the group tries to escape but finds themselves locked inside with no means of communication. As tensions rise and trust begins to break down, they attempt an amateur exorcism in an effort to save one of their friends from the demon. However, instead of resolving the situation, they inadvertently unleash a more powerful and vengeful spirit, one with a clear motive to kill them all. The teens' only hope for survival lies in uncovering the asylum's hidden secrets and finding a way out before time runs out.
