Released shortly after the liberation of France, (French: Un ami viendra ce soir ) is a 1946 thriller that explores the fine line between sanity and deception during wartime. Directed by Raymond Bernard , the film is set within an Alpine sanatorium where Resistance fighters hide in plain sight by posing as psychiatric patients. Plot Overview
The story follows Commander Gérard and his band of guerrillas who have established a secret base in a mountain nursing home. To avoid detection by occupying Nazi forces, the fighters blend in with the mentally ill, leading to a "dialogue of the deaf" where the audience and characters alike struggle to distinguish true lunacy from calculated performance. The tension peaks as rumors of a "knockout punch" against the Nazis circulate and suspicion grows regarding a Swiss doctor who may be a German spy.
