Helen Alving leads an outwardly contented life. On the eve of the 10th anniversary of her husband's death, she is about to open an orphanage as a memorial to him. To mark this occasion, her bohemian painter son Oswald has returned from Paris. Helen plans to take the opportunity to tell Oswald the truth about his father. But ghosts of the past erupt during an eventful evening, bringing the facade of civilised family life crashing down.
