A group of complete strangers find themselves in a precarious position, trapped inside the walls of an enormous hi-tech facility, in some unknown, yet familiar, location. With strange marks on their bodies and no memory of how they got there, they work together and traverse the compound looking for an exit. But they soon begin to realize there's much more to their plight than they initially thought. Each passing moment presents not only more questions, but deadly challenges and startling discoveries of things that shouldn't even exist.
But as hours turn into days, the group becomes more desperate--their paranoia almost unmanageable. They struggle with the increasing feeling that whoever or whatever is orchestrating this rat maze has much bigger plans for them. As they continue forward, hanging onto their last shreds of hope, the unexplainable occurrences and bizarre happenings eventually lead them to one question that should give them all the answers they need. What is Hayling?
