Desert Nights

A gang of thieves rob an African diamond company of diamonds worth $500,000, with two of its members posing as Lord and Lady Stonehill (who are expected to pay a visit). They kidnap its manager, Hugh Rand, and head into the Kalahari Desert. After a few days in the sweltering heat, three of the crooks decide to take their chances in Cape Town instead and demand their share of the loot. Steve ("Lord Stonehill") gives them worthless glass.
