Plot
Adventure-seeker Ted Osborne (Phillip Reed) and his fiancée Carole (Virginia Grey) are at a cafe in Singapore, looking for a charter to an island supposedly inhabited by dinosaurs. They come across the ruthless, two fisted, alcohol-suffering Captain Tarnowski (Barton MacLane). They decide to talk, and Osborne asks if Tarnowski is willing to give them a charter in his ship to the unknown island. Initially Tarnowski refuses, but then Osborne tells that during World War II he was a pilot in the US Navy. He had flown over many remote islands, and on one he reported seeing large, moving creatures that looked like Dinosaurs. He shows Tarnowski a photo, and the captain finally agrees to take them there. Before departing, Tarnowski introduces them to John Fairbanks (Richard Denning), an old friend of his, who agrees to help them with their quest. Fairbanks and a group of friends had been shipwrecked on the island with Fairbanks being the lone survivor of attack by the dinosaurs. As Fairbanks had been drinking incessantly to forget the events of the past since his rescue, his account of the dinosaur island was believed to be the result of alcoholism and insanity. Since Fairbanks and Osborne's stories collaborated, Tarnowski agrees to allow his ship to be hired, but specifies that no one in the crew be told of their destination.
They sail aboard Tarnowski's ship, heading for weeks in the direction of French Polynesia, where the island is supposed to be located. During the voyage, it becomes clear that Fairbanks is obviously becoming attracted to Carole, even though she is the fiancée of Osborne.
