"Maine-Ocean" is the name of a train that rides from Paris to Saint-Nazaire (near the ocean). In that train, Dejanira, a Brazilian, has a brush with the two ticket inspectors. Mimi, another traveler and also a lawyer, helps her. The four of them will meet together later and live a few shifted adventures with a strange-speaking sailor (Mimi's client).

Jacques Rozier followed Bernard Ménez's tour in 1984 after the surprise success of his song "Jolie poupée". From a timecoded video in the possession of Jacques Rozier, post-production work was carried out in 2001 under the supervision of the director for his retrospective at the Center Pompidou. The element resulting from this work was digitized by the Cinémathèque française at the Hiventy laboratory in 2021.
