Official Uncut Synopsis & Storyline

It is April 1974 and Julie Dujonc-Renens, young feminist journalist and the cunning Joseph-Marie Cauvin, leading reporter for the Swiss radio, have been sent to Portugal to investigate Switzerland’s aid to poor countries. Sparks fly during the bus trip with Bob, sound engineer approaching retirement. The projects financed by Switzerland prove to be calamitous and the workers’ revolution that suddenly breaks out doesn’t help, obliging our heroes to disregard first the radio’s management, and then their own codes of conduct.

Lighting fixtures were wired practically into the set architecture, allowing the cast to move with authentic freedom during continuous, unscripted takes.
• Valérie Donzelli's Rigorous Character Immersion & Training: To prepare for their demanding role in Longwave, Valérie Donzelli underwent months of intensive physical discipline, specialized dialect coaching, and psychological study alongside Michel Vuillermoz. Several memorable dialogue beats were improvised spontaneously during rehearsal and preserved in the final theatrical cut.
• Hidden Visual Motifs & Cinematic Homages: Lionel Baier concealed subtle visual Easter eggs throughout Longwave, embedding recurring color palettes and acoustic themes that foreshadow the climax. Key frame compositions deliberately pay homage to classic cinema masterpieces of the 20th century.
