Howard and his wife Daisy, both retired and residing in a quiet suburban villa, lived an emotionally sparse life following the loss of their only son. The couple's pattern of a peaceful but monotonous life is disrupted when Daisy, delusional due to a medical condition, identifies a young waiter, Luke, as their deceased son during one of their restaurant visits. Taking advantage of this, Howard hires Luke to pretend to be their son and visit them weekly for which he provides additional compensation. Despite concerns about Luke's integrity, things go well initially, and Daisy's condition shows some improvement. However, when their home is robbed, Luke becomes a prime suspect. Even though he is later found innocent, the trust is broken and Luke is kept away from the couple. Daisy's health deteriorates and she passes away. On her memorial, Luke leaves a sunflower with a note, showing his sincere affection for the couple. In the end, Howard invites Luke to visit with his girlfriend, bringing some warmth back into his lonely life.
