The guests are locked in a room for 38 hours without food as they are forced to play Masha’s dark games.

Nine strangers have been thrown together at a remote health resort.

But Tranquillum House is owned and run by an equally wounded and strange woman who is determined that her guests’ lives will never be the same again after their ten-day stay.
