Desert Nights

Blazing sun. Burning sand. And scarcely a drop of water. In the vast trackless wastes of the Kalahari Desert, two diamond thieves and their hostage struggle for survival. The thieves have a fortune in gems, but their hostage -- the manager of the robbed mine -- has the knowledge to lead them to safety. John Gilbert, starring in his final silent movie, is in gallant form as the mine manager who outwits his captors: a slick conman and the beautiful woman posing as his daughter. (And when famed screen lover Gilbert meets a beautiful woman, fans know it's more than the desert that's going to get hot!)
