In 1852 Richard Francis Burton, the legendary explorer and author, fell in love with a Persian woman while in the British Army. When her parents discovered the affair, they poisoned her. Devastated and vulnerable, Burton camped out in an opium den. But the British spymaster, Hodgson, needed Burton and his unique talents for a mission: pose as a Muslim on the Hajj, and when it's over, steal a woman from a harem in Medina.
