Our scene opens with two samurai, running through the tall, oppressive reeds. One is wounded, and the other is helping him along. Suddenly, their flight is interrupted, their lives coming to a sudden and grisly end at the points of vicious spears. Their desperation permeates the very opening frames of Onibaba and sets the tone for the entire film. Onibaba is a tale of deceit, murder, sexual frustration, and the monstrosity that lies in the hearts of ordinary people.
