At a single touch, they are pulled from their lonely lives into to a wondrous castle filled with winding stairways, watchful portraits and twinkling chandeliers. In this new sanctuary, they are confronted with a set of clues leading to a hidden room where one of them will be granted a wish. But there’s a catch: if they don’t leave by five o’clock, they will die.

As time passes, a devastating truth emerges: only those who dare to share their stories will be punished.
