Snake and Harry, two professional diamond thieves gatecrash the funeral of Miss Amelia Devonport, who was the late owner of the fabulous Devonport diamonds. Snake and Harry plan to impersonate relatives of the late Miss Devonport to get information on the diamonds and where they could be hidden in the old Devonport mansion. Then they plan to steal the famous stones. Unbeknownst to Snake and Harry, two cops, Capt. Theunis van Staden and his young partner, John Smith have also gate crashed the same funeral, and are, um, also posing as relatives. The two policemen received an ‘anonymous tip’ earlier in the week that led them to believe that two thieves, masquerading as relatives of the deceased, would crash the funeral and steal the diamonds. Their task: to find the location of the famous stones and use them as bait to trap the diamond thieves into revealing themselves. It all gets rather complicated when each one of them decides to call himself ‘John Smith’ in this hilarious farce script.
