Timing is everything when it comes to avoiding the treacherous tide in the Mont Saint Michel bay, in French Normandy.
Two British couples learn this the hard way when they decide to cross the sandy bay without a professional guide. Quicksands, heavy wind and darkness make matters worse.
But an unexpected danger aggravates the situation. The bay seems to host a ghostly "presence", and their friend Charlotte does not seem to be on their side.
