Lisa Walker is a business executive who has grown used to being alone, though she does not much care for it. Her birth parents left her, and she spent most of her childhood with Stanley, a foster father whose affection cooled after her adoptive mother died.

She questions the delivery man and visits the flower shop, but the sender stays unnamed.
