annings and Negri are Egyptians involved in a scam milking tourists out of their money, by having the girl lend her eyes to the "mummy" from inside an empty sarcophagus! When a British lord and adventurer comes to visit, she falls in love and leaves with him to England. Needless to say, Jannings – who, naturally, has feelings for Negri himself – follows them (conveniently in the employ of another English aristocrat and friend to Liedtke) in order to exact his revenge.
