Written by Howard Dimsdale, the film is about a beautiful concentration-camp refugee who waits in Cuba for permission to enter the United States.

After World War II, immigrants in Cuba who are refused visas try to sneak into the United States illegally with the help of a human smuggling ring run by Palinov, a Levantine café owner.

During his dangerous undercover investigation, Pete meets Marianne Lorress, a penniless Austrian refugee of the Buchenwald concentration camp who is waiting to be smuggled into the U.S. by Palinov.

Palinov discovers Karczag's true purpose and exposes Pete to Marianne, who angrily decides to proceed with the smuggling trip.
