The plague is making its way through Thebes. The oracle says the city is doomed because the murder of King Laius has remained unpunished. His successor Oedipus wants to free the people, who suffer greatly, of this curse. He leads the investigation personally. This is not the first time for Oedipus. He previously solved the riddle of the sphinx. He is determined to leave no stone unturned. The outcome is devastating: to everyone’s great dismay – not in the least his own – Oedipus himself turns out to be the culprit.
