The film combines clips from Tarkovsky’s films with footage of Tarkovsky on the set of his last film The Sacrifice and on his deathbed, during the final stage of his battle with cancer. The film mostly relies on images, with only sparse commentary, and concentrates mainly on giving insight into Tarkovsky’s work and philosophy and on exploring the intersections between his private life and his work. The film starts with a scene from Tarkovsky first film Ivan’s Childhood and ends with a parallel scene from his last film The Sacrifice. It shows the reunion of Tarkovsky with his son Andrei Jr., who had been allowed to leave the Soviet Union only after Tarkovsky was diagnosed with terminal lung cancer.
