The film begins with “Alex” (Alan Rickman) driving toward Winnipeg when he picks up “Vivienne” (Emily Hampshire), offering her a ride. She proves to be an amusing companion, but their journey ends abruptly in a collision with a truck, resulting in her death. Still reeling from the accident, Alex decides to seek out Vivienne’s mother, “Linda” (Sigourney Weaver), intending to express his regret and sympathy. However, what he discovers upon arriving at her door is completely unexpected; she reacts to the tragedy with an unsettling calmness, readily dismissing his involvement before closing the door in his face. Fortunately, he has a gift intended for her, which allows him entry into the house where he’s offered some rather unpleasant-tasting tea and introduced to a woman who seems to be somewhere on the autism spectrum. Her home is meticulously tidy, she's an avid cleaner, and surprisingly still sleeps in a bunk bed from when she was three. Alex then proposes staying to help her out, and over time they begin to build some sort of rapport as the funeral draws nearer. The neighbors offer condolences, but he’s cautioned against getting close to “Maggie” (Carrie-Anne Moss), who is apparently a prostitute, and the local police officer “Clyde” (James Allodi) isn't thrilled when Alex starts befriending Maggie after walking her dog a few times. As the day of the funeral approaches, each character gets an opportunity to develop, revealing their individual struggles against the backdrop of mourning in middle America. Rickman is naturally skilled at portraying a detached and sarcastic personality, which he does well here—but also brings a considerable amount of empathy to his role. Moss delivers a strong performance as well, and regarding Weaver, I believe this may be her best work yet. She embodies the character of an intelligent and fully functional woman living within a self-constructed shell that is now exposed by the loss of her daughter, whom she considered “very interesting”. There’s a palpable connection between the characters; sentimentality is largely absent, and there are some genuinely funny lines as the story moves toward what feels destined to be an open-ended but ultimately rewarding conclusion (assuming the garbage collectors arrive). The film has an intimate feel, and its lack of melodrama makes it quite touching and relatable, definitely worth seeing.
