Three Oxford graduates -- Robert Allen (Paul Richter), Carl Langland (Olaf Fonss) and Indian Prince Ayan (Conrad Veidt) -- pledge to remain devoted to one another. It doesn't take long for the oath to be broken, as the prince believes that his wife, Princess Savitri (Erma Morini), has been unfaithful with Allen. He decides to bury his wife alive and has Yogi Ramigami (Berhard Goetze) travel to England to fetch Langland. But when he orders his old pal to build him a tomb, he refuses.
