Spoofing the classic Beau Geste and a number of other desert motion pictures, the film's plotline revolves around the heroic Beau Geste and his brother Digby's misadventures in the French Foreign legion out in the Sahara, and the disappearance of the family sapphire, sought after by their money-hungry stepmother.
The film was shot on location in Madrid, and in Ireland at Ardmore Studios in Bray, and on location at Kilmainham Gaol in Dublin and Adare Manor near Limerick.
