Madame ou Monsieur is a lyrical short film about grief, kindness, and the power of unexpected human connection. Through delicate performances, handwritten letters, and a minimalist design, the film follows Vincent, a man adrift in monotony, as he finds new purpose in his correspondence with Colette, a stranger whose words breathe life back into his world. When her absence leaves him shaken, Vincent transforms loss into legacy, choosing to continue her ritual of writing letters to strangers. Subtle yet emotionally resonant, the film invites audiences to reflect on how even the smallest gestures can bridge silence and touch another life.
