Seven people, all strangers, all from different walks of life, awaken in a giant cube shaped room with hatches on all six sides. With no memory of how they got there, they soon discover that this is just one of thousands of rooms in a giant cube shaped structure. The rooms are constantly shifting and some rooms are boobie trapped. With no food or water and their numbers dwindling, they must work together to avoid the traps, discover the secret of the cube, and find a way out, if there even is one. Little do they realise, their biggest threat of all may be each other.
