Just before the end of World War II, the Yalta Conference was held by the “Big Three” Allied leaders: Franklin Delano Roosevelt of the United States, Winston Churchill of Britain, and Joseph Stalin of the USSR. Japanese theater company Seinendan reimagines their conversations about postwar rule and power as a darkly humorous satire.

Theatre 1 (Observational Film Series #3) is a feature length documentary, which closely depicts the world of Oriza Hirata, Japan's leading playwright and director, and his theatrical company, Seinendan. By depicting them, the film leads the audience to revisit fundamental but timely questions: What is theatre? Why do human beings act?
