Two very different groups arrive at the same place on the same night after the same thing, a hoard of ancient treasure buried deep within a massive, abandoned Victorian bath house.
One is a group of professional cat burglars, on their final heist and the other is a bunch of young, misfit jobseekers on a team building exercise.
There's only one thing standing between them and riches beyond their wildest dreams, and it's not the other group.
A deranged security guard has spent decades preparing the building against invasion and has set up deadly and disturbing traps throughout the labyrinth.
Who will survive the night? How many pieces will they be in? When will the next trap be sprung?
