It's not everyone who's invited to start an air force. But Biggles is, by the Maltovian ambassador. He refuses—at first. But sinister threats by the representative of neighbouring, power-hungry Lovitznia make him change his mind. Soon, Biggles, Algy and Ginger are flying the three solitary planes that make up the Maltovian air force. They face danger in the skies, but there's danger on the ground too—in the form of treachery and intrigue. Biggles and his friends, of course, face it with all their renowned skill and courage.
