Early aviation barnstormer Al Wilson became an acttion star in silent movies with films like this, using a simple adventure story about stolen diamonds in Africa to support loads of bi-plane action.

A family diamond mine in South Africa causes great problems to owners Dr. Cecil James (George B. French) and his daughter, Grace (Helen Foster). Accompanied by her maid, Mira (Myrtis Crinley), Grace and her father decide to go to Africa to investigate. They arrange to meet Jack Woods (Joseph Bennett), manager of the Consolidated Diamond Mining Co., who has used the excuse of a native plague to close the mine and hold up shipments.

Being advised by his men of the doctor's visit, Woods has the party waylaid by Swahili warriors. The two girls flee and Wood "rescues" them, taking them to the a building at the mine site. Fearing for their safety, back home, Sir Henry Blake sends his son, Art (Al Wilson), after them, and he succeeds in eluding the gang at the mine.

Art sneaks into the Swahili village and frees the doctor but is himself captured and thrown in a lions' den, from which, however, he escapes. Woods forces Grace to accompany him in a getaway by air. Art pursues in another aircraft and in an air battle, subdues the villain, who falls to his death.
