Even though Americans embraced The Cabinet of Dr. Caligari, they seemed a bit puzzled by this fanciful German-made melodrama. 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. The prince holds him prisoner, and his fiancee, Laura Valmy (Mia May), comes looking for him. She too is captured and Ayan, with Ramigami's help, subjects all of them -- Langland, Allen and Laura -- to cruel torture. Finally Langland tries to rescue Savitri from the prince's troops by carrying her across a suspension bridge, but she sacrifices herself by cutting the bridge's ropes and falling to her death. Meanwhile, the prince renounces his religion, damning him to a fate worse than death.
