Fog Island is an ex-pirate lair with secret passages, hidden compartments, underground vaults and booby traps. Manipulated by Leo most of the guests end up in a locked room which begins to fill with water...
Interesting and enjoyable film with noir touches though it doesn't make a lot of sense. Everyone is backstabbing everyone else (sometimes literally), even lovely step-daughter Sylvia (Veda Ann Borg) isn't wholly above reproach.
