Thea von Harbou's colorful plot stretches over two feature-length films, with twists and turns worthy of a serial. Ayan, the powerful Maharajah of Eschnapur, has lost his beloved wife, the beautiful Princess Savitri, but not through death. He plots revenge against Savitri and her lover MacAllan, an English officer. Ayan vows to build a tomb to his dead love; he'll supply the mausoleum's occupant. A yogi, Ramigani, prophesies that revenge will ruin the prince's life. Ayan sends the yogi to Europe to hire an architect, Herbert Rowland, who is sworn to secrecy about his commission. Rowland's fiancee Irene follows him to India, and the adventure begins.
