In The Wake Of Mary Celeste

Dr. Quest is on an adventure to find the famous Nova Scotian ship - Mary Celeste's remains. A century ago, this cargo ship sank into the sea mysteriously, and the crew was never found. As he drives down into the depths of the sea, he discovers what look like crop circles at the bottom of the Sargasso Sea - and a graveyard of ships in an area barren of marine life.
