The crew of the Seaview, the world's first privately owned nuclear submarine, explores oceans and seeks answers to the world's problems. They encounter espionage, environmental catastrophe, nuclear doomsday scenarios, and more than their share of undersea monsters.

Hallucinations plague the Seaview men who are on a mission to deliver a secret missile.

Nelson, Crane and Morton are transported to an alien planet.

Nelson nearly loses his life when he becomes interested in a friend's scientific experiments on animals.

The Seaview plays a deadly game of cat-and-mouse with a mystery sub.
