Jean, Nadia, and King are rescued from the ocean by a passing American battleship called the Abraham. Its captain, Melville, and his first mate Holland, are on the trail of a supposed "sea monster" responsible for sinking countless ships in the Pacific Ocean. Jean is intrigued to be aboard the vessel, but Nadia is gravely suspicious. While on the ship, they also meet Ayerton Grenavan, a flamboyant "scientist" who claims to be funding the pursuit. That night, the Abraham is attacked by a mysterious and dangerous presence. A torpedo finally strikes the Abraham, causing Jean, Nadia, King, and their aircraft to be thrown overboard into the ocean again.
