The Sea is Boiling Hot

An erupting volcano spews molten lava into the sea during an undersea archeological expedition. Roberto Bellini, a scientist friend of Carter Primus, explores a sunken Etruscan galley off the Italian coast, But before he can surface, nearby Mt. Ewa erupts, pouring molten lava into the sea. The waters heat to such a degree Bellini's air tanks explode, forcing him to take refuge in a diving bell. Primus, wearing a special asbestos diving suit, enters the boiling waters in an attempt to save his friend.
