This Italian documentary chronicles the making of the penultimate film of deceased Russian director Andrei Tarkovsky and famed Italian screenwriter Tonino Guerra. The story begins as the two begin scouting locations in Italy for Tarkovsky's film, Nostalgia. Though Guerra shows him many beautiful places, Tarkovsky rejects them all until they go to the medieval town, Bagno Vignoi, which contains in its main square, a famous Roman bath. The two then begin to converse about filmmaking and life with Guerra asking questions in Italian and Tarkovsky answering them in Russian.
