Who knows what evil lurks in the hearts of men? The Shadow knows. Lamont Cranston, lawyer by day, but known to the underworld as the Shadow, fights crime with the aid of his lovely secretary and assistant, Margot Lane.
Today, the shipping business is in turmoil when ships are mysteriously disappearing. The Navy has no answers, but the Shadow offers his help, and believes the whole mystery revolves around one person. Lamont and Margot take a ride on a Navy cruiser, and sea plane in search of the ship’s graveyard.
Things look bad when the plane has to crashland. What is the secret that has been pulling ships, and sea planes to their destruction? Besides surviving crashes, the Shadow has to face native canibals, volcanoes, wierd religious sacrifices, and a local figure known as the White God.
Can the Shadow poke holes in the native superstitions? How will he expose the White God for the crazy charlatan that he is? The first thing to do is identify what’s going on, but it may be another to sabotage the scheme, and bring justice to bear.
