Brittany, early 1980s: With political and cultural transition in the air, little brother Philippe (Thimotée Robart) stands in awe of moody, indulgent, but charismatic older sibling Jérôme (Joseph Olivennes). The two are passionate about operating a post-punk pirate station named (in homage to Joy Division) Radio Warsaw. Jérôme is the silver-tongued but mercurial on-air DJ, Philippe the shy technical support with a talent for sonic collage. Both fall for single mother Marianne (Marie Colomb), just before Philippe has to begin his compulsory year of military service abroad in Berlin. Vincent Maël Cardona’s feature-film debut (which premiered in Directors’ Fortnight at last year’s Cannes) is a heady, emotionally rich reconstruction of an intense moment of social and cultural change, complete with an excellent soundtrack.
