A high-powered executive wakes up alone, trapped inside a wooden cell, with food, water, and a bed but absolutely no idea how he got there. As the days pass, panic turns to anger, grief, and finally despair. When he discovers a woman trapped in the box next to his, they soon realise that cooperation is their only hope of escape. They begin to trust each other, their shared suffering brings them closer, and they reveal their darkest, most unspeakable secrets. As the manipulative game of their jailer is slowly revealed, neither can be sure whether the other is friend, foe, or something else entirely.
