Dagmar Brink, Eva Henning, is a young woman who attends a wild party and sits at the piano, hoping to evoke something special with a requested tune. She begins, then abruptly stops in distress, and walks away into the night through central Stockholm. On a bridge, she encounters a drunk artist; after a brief exchange, he persuades her in a moment of frailty, and though she gives him money for his sketch, she does not keep the payment herself. When she finally reaches her apartment, she ties a rope to the ceiling and hangs herself, a decision that shatters the quiet of her building. The next morning, a housekeeper discovers her body, and the calm facade of the neighborhood begins to crack open.
The police arrive and question the neighbors, trying to piece together who Dagmar was and what might have driven her to take her own life. Dagmar Brink appears to be something of a loner, and those who knew her describe a girl who seemed sweet and kind, yet elusive. The investigation becomes personal for the people closest to her, especially Anders Wikner [Ulf Palme], a writer who lives in the flat next door. He is deeply shaken by the tragedy and takes it upon himself to uncover the truth about Dagmar, delving into memories and conversations that others would rather leave behind.
Anders sets out to talk to the handful of people who encountered Dagmar in the days and hours leading up to her death. He seeks out Elias Körner [Anders Ek], an artist who painted a portrait of Dagmar, and he revisits an old bank manager who had a cold, formal meeting with her. He also tries to track down a woman who once shared a room with Dagmar, an ex-husband who may hold a sliver of motive, and the singer who performed at the party the night of the suicide. Each conversation reveals fragments of Dagmar’s life, hinting at desires, disappointments, and unresolved tensions that linger beneath the surface.
Dagmar’s closest companion at home is Britt Wikner [Birgit Tengroth], Anders’s wife, who also carries a memory that casts new light on Dagmar and the night in Dagmar’s apartment. Britt’s recollections intersect with Anders’s inquiries, suggesting there may be more to Dagmar’s story than a single choice made in desperation. The pair’s shared concern adds another layer to the unfolding mystery, as they weigh rumors, misread signals, and the fragile nature of the friendships surrounding Dagmar.
What follows is a tapestry of flashbacks, each one showing a different encounter with Dagmar and hinting at the ways her presence affected the people around her. The film moves between present-day questions and past moments, gradually assembling a mosaic of Dagmar’s life from multiple viewpoints. While these recollections offer clues, they also raise new questions, leaving the ultimate truth tantalizingly out of reach. The narrative stays true to the emotional core of the tragedy—how a single night can ripple through a community and how well-meaning curiosity can uncover more questions than answers, all while maintaining a quiet, somber mood that lingers long after the final image.
