It's 1948. A pair of impoverished pilots working in the African bush, the "super" Mike Patton (George Reeves) and the super-smarmy Bob Simpson (Ralph Byrd) learn that the Dutch millionaire father of long-missing Greta Vanderhorn (Wanda McKay) has offered a substantial reward for his daughter's return. She was lost when her plane went down somewhere in "the dark continent" just as the second World War began. They fly off to the area where Greta's plane vanished six years ago. Eventually, Mike, Greta, Bob, and Wanama escape and make their way back to America.
