Synopsis:
A crew of sailors decide to settle the mystery of the Mary Celeste, a ship whose crew disappeared without a trace years earlier. The crew sets sail with a new vessel, the Mary Celeste II, which is identical to the original. After the start of their voyage nothing is heard from them.

Weeks later the Boy Commandos discover the Mary Celeste II abandoned at sea, just like the original. They follow an oil slick back to an island where they are attacked. The Commandos discover crooks living on the island.

The crooks, in the guise of sailors, used the Mary Celeste II to escape authorities and reach the island where they have plastic surgery to alter their appearance. They hoped to use the mystery of the Mary Celeste to cover their disappearance, but the Boy Commandos capture them and shut down their operation.
