The Flaming Signal plot
During a record-breaking attempt to fly from the mainland to Hawaii as quickly as possible, pilot Jim Robbins and his faithful companion Flash are caught in a storm and crashed near the mysterious island of Tabu. There, Jim not only meets the beautiful vicar's daughter Sally, but also the seedy Otto Von Krantz, who abuses the local population for his own gain. But when he goes a step too far and the high priest kills Manu, the people turn against him. While the search for Jim is in full swing, Flash comes to the rescue of his owner.
