Rowland falls sick with leprosy while Mac Allan is captured by the Maharajah, who offers Irene a deal: one night with him in exchange for letting Rowland to be cured. She accepts, but tries to commit suicide.

Ayan, Maharajah of Eschnapur, believes that his wife, Princess Savitri, has been unfaithful to him with officer Mac Allan. He decides to bury her alive, so he sends the Yogi Ramigani to England to look for Herbert Rowland, an architect; but when he orders him to build a tomb, Rowland refuses.
