Special agent Sheldon (Robert Wilcox) is sent to a desolate island where Danel (Peter Lorre) keeps convicts for forced labour. Danel took his wife Lorraine (Rochelle Hudson) to the island, but the promise of a tropical paradise was not exactly true; meanwhile she hates him. Sheldon now has the double task to put an end to the slave trade methods of Danel and help Lorraine to escape, while the prisoners don't sympathize with him, either.
Peter Lorre (previously starring in the Mr Moto series) is a brilliant villain in this movie. With his quiet voice and mild manners, he becomes menacing like a devil in disguise. I remember Rochelle Hudson from "The Savage Girl", she also appeared in one of Lorre's Mr Moto movies. The problem of the movie is that the hero (Wilcox) doesn*t make a big impression; partly that is in the script because he has to keep his mouth shut not to reveal his identity to Danel. Still the movie is worth watching for its dominant villain.
