The day of her celebration arrives, and Clarissa (Vanessa Redgrave) feels some nervousness. Her husband, a politician (John Standing), has abandoned her for a midday meal on this significant occasion, so she goes out to purchase flowers before discovering an unexpected guest awaiting her return. Peter (Michael Kitchen) shares a past with her, and as the story progresses, we gain insight into that history through flashbacks featuring Alan Cox and Natascha McElhone portraying their younger versions. These sequences illustrate the progression toward choices and decisions that perhaps one or both would now prefer to have handled differently. The film also provides a gentle depiction of the political climate in Britain shortly after World War I concluded—the aristocracy attempting to preserve its former power, the growing role of women, the shifting political scene, and the decline of unquestioning respect are all incorporated into the narrative as the party approaches and its hostess experiences anxiety. Simultaneously, there's a more engaging plot unfolding with Rupert Graves in a believable performance as Septimus Warren Smith, who has returned from the war and is struggling to adapt to peacetime life, causing considerable distress for his wife (Amelia Bullmore). This isn’t helped by psychiatrist Sir William Bradshaw (Robert Hardy). Overall, this is an impressive-looking drama showcasing a collection of well-known British actors, but Redgrave's performance veers slightly toward being dull. Aside from the emotionally intense moments with Graves, the film's momentum struggles to move beyond a slow pace as it wanders along, presenting a rather uninspired look at the lives of people in whom I mostly lacked investment. It’s agreeable enough and represents the sort of production that Britain excels at, but it feels somewhat thin when it comes to character development.
