An elegant young woman in her messy room answers the phone call from her lover. This one, who intends to leave her, tries to make her understand what he is up to without hurting her too much, hypersensitive as she is . All means are good: big words, cajolery, denial, lies. As for the woman, who senses that this is the end, she desperately tries to win him back, passing from tenderness to passion, from the threat of attempted suicide to calm, from regret to outbursts of violence.
