The third and final film in a trilogy with Don't Let It Kill You (Il ne faut pas mourir pour ça) in 1967 and The Old Country Where Rimbaud Died (Le Vieux pays où Rimbaud est mort) in 1977, the film updates the story of Abel Gagné (Marcel Sabourin) in his middle age.In the film, Abel Gagné has been working for many years as the owner of a small aviation company, but has not personally flown a plane since the death of his friend in a plane crash 15 years earlier. On the day he decides to finally fly again, however, various complications crop up to interfere with his plan, including the return of his estranged father Napoléon (Claude Blanchard) whom he has not seen in 50 years. Lefebvre described the trilogy's themes as being about family relationships, with Don't Let It Kill You as addressing the mother, The Old Country Where Rimbaud Died as addressing ancestors, and Now or Never addressing the father. The film's cast also includes Julie Ménard as Monique, the daughter of Abel's dead friend; Jean-Pierre Ronfard as Abel's business partner; and Micheline Lanctôt as Arlette.
