Two young school teachers decide to visit the Yorkshire moors where, a year earlier, a friend of theirs disappeared. They find an isolated mansion on the edge of a foggy, desolate marsh. In it, James Mason, a pianist recovering from nightmares, is taken care of by a housekeeper and a handyman. Something mysterious is going on, with doors slowly closing and warnings about the marshland.
This is early Mason, but he already has the romantic but driven and possibly violent persona down pat. The movie itself is pretty good but the VHS transfer isn't. The transfer is shaky, a little out of focus and much of the action in the night scenes (and there are a lot of night scenes) gets lost. Still, if you like old, dark houses, stormy nights and James Mason, it's worth the price.
