While normally a death in the family, brings people together, that is just not the case for Lonnie Grambell. After the mysterious death of his older brother, his rich parents decide to send him away to boarding school, cutting off all communication for the better part of a decade. Now on the night of his graduation, Lonnie finds his world flipped upside down once more as he receives a formal invitation asking him to return for the summer before college.

Driven by curiosity and an urge for answers, he ventures home only to find that it is far from the family reunion he was expecting. Arriving at his parents mansion in the New York countryside, he is faced with a warped version of the world he remembered as a child. Bombarded with lavish meals, expensive gifts, and an invitation alongside his parents to the most exclusive and secret gala in New York, he feels that it all must be a dream.

That is until he wakes up after the party, and finds himself in a nightmare. Balancing a splitting headache and a loss of memory, he comes to realize that he is in some kind of twisted underground maze full of hidden cameras, deadly traps, and unspeakable horrors behind every corner. Suddenly in a fight for his life, Lonnie must overcome all odds and best his captors at their own game.

The only question is... what are the rules.
