A small community residing in Arlington Heights, Illinois has been unheard of without the exception of the 1,259 people that live there and the cities surrounding them. The most interesting and secretive part of the small town is the Blue River Sanitorium, which was built in 1876, but later abandoned. The sanitorium was primarily used to care for the criminally ill and for other patients with long-term illnesses. Being abandoned in 1957 due to the harsh treatments on patients, also leading to the patients mysteriously disappearing, the stories surrounding the building that a group of friends, Jacob, Jonathon, Olivia, and Harper soon get curious about. Will they go in and check out the building? Will they continue to walk past the asylum pretending it doesn't exist? Or will they find out the truth and change their view on the building? Having to pass the building twice a day without getting the creeps is tricky enough, but what happens if they do enter?
