However, his stepmother, Sudabeh, the Queen of Iran, develops a burning sexual desire for him. Refusing her advances, Siavash will have nothing to do with her plans for intercourse. She fakes a rape and abortion scene and blames the double calamity on Siavash who is forced to prove his innocence by riding through a colossal mountain of fire. Despite his proven innocence, the Shah eventually grows cold towards Siavash as he does not want to punish the woman he loves or anger her father, a powerful ally in the East. Siavash finds no alternative but to go into self-imposed exile in the mythical land of Turan, and seek shelter under the rule of Afrasiab, the tyrannical arch enemy of the Iranian Shah. Finally, Siavash is beheaded by Afrasiab's henchmen. His wife manages to escape to Iran, where her son becomes the next Shah, Kay Khosrow. Finally, Shah Kay Khosrow takes a terrible revenge on Afrasiab and inflicts a heavy defeat on the Turanian army.
