King Laius of Thebes hears of a prophecy that his infant son will one day kill him. He pierces Oedipus' feet and leaves him out to die, but a shepherd finds him and carries him away. Years later, Oedipus, not knowing he was adopted, leaves home in fear of the same prophecy that he will kill his father and marry his mother. Laius journeys out to seek a solution to the Sphinx's mysterious riddle. As prophesied, Oedipus and Laius cross paths, but they do not recognize each other. A fight ensues, and Oedipus kills Laius and most of his guards. Oedipus goes on to defeat the Sphinx by solving a riddle to become king. He marries the widowed Queen Jocasta, unaware that she is his mother. A plague falls on the people of Thebes. Upon discovering the truth, Oedipus blinds himself, and Jocasta hangs herself. After Oedipus is no longer king, Oedipus's brother-sons kill each other.
