Feature Film(2006)

Original title: Long métrage

A couple wordlessly makes love then she dresses and leaves. He follows her to the door and kisses her. She hurries off, a bag over her shoulder. He discovers that a black thread, probably from her stockings, has caught on a bolt near the door and it's unraveling behind her. He follows, gathering the thread as he runs. He reaches Orly; is he in time?
