Marlo is a cook and aspiring filmmaker trying to capture all that is ephemeral on hard drives. Eloïse is an actress who attends endless auditions while still young. Finally, Liam is a jazz-obsessed musician who locks himself away in a world of music and cigars. The film explores these three diverse existences trying to find their place in an ever-changing world, under the unchanging glow of the remnants of the Betelgeuse supernova.
