The film’s tragic climax hinges on a devastating binary: Bettina’s pregnancy. In a cruel twist of heterosexual expectation, the news that Marc is to be a father arrives at the exact moment he attempts to commit to Kay. Here, Lacant refuses the easy catharsis of a happy ending. Marc chooses the baby. He chooses the uniform. He chooses the freefall of social safety over the freefall of love. The film’s brutal honesty is that this happens every day. The final act is a masterclass in quiet devastation. Kay, heartbroken and exposed, is transferred to another precinct. Marc, having lost both his lover and his integrity, is left alone in a sterile apartment, cradling his infant son. The final shot, echoing the opening sequence, shows Marc running alone through the forest—not as a release, but as a penance. He is still falling, but he has forgotten what he was falling toward.
