Cast & Crew
August Bolte, a wealthy planter in New Posen, a German possession in East Africa, is hated by the settlers and the natives, who call him Mamba (the name of a poisonous snake) because of his extreme cruelty. On a visit to Germany, Bolte marries Helen, the beautiful daughter of Count von Linden, who sacrifices herself in a distasteful marriage to save her father from disgrace and prison. Revolted by Bolte's coarseness, she finds consolation in Karl von Reiden, a young officer returning on their boat. At a reception given by Bolte, he flaunts his bride before the guests, including Karl and Major Cromwell, his close friend; when a native declares Bolte responsible for the death of his daughter, Helen is terrified by her husband's wrath, but news arrives of war between England and Germany. Bolte escapes arrest for evading conscription but is killed by the natives; Karl goes to rescue Helen, and they are saved from a native onslaught by a British detachment.
