Miss Marquette, an adoption agent, agrees to a highly unorthodox home visit with prospective parents outside of office hours, much to the disapproval of her colleague Dudley. She is unable to explain her decision beyond being inexplicably moved by the client's voice. The pair arrive at night at a dilapidated mansion, where they are greeted by the enigmatic Count and Countess. The couple express a strong desire to adopt a child and ask the agents to bypass standard procedures. While Miss Marquette is charmed and willing to proceed, Dudley remains skeptical. To prove their capability as caregivers, the Count and Countess telepathically summon four children who are already in their care.

Some time later, Miss Marquette prepares to deliver a new child to the Count and Countess. Despite Dudley's warning that the boy has a reputation as a "problem child," she proceeds. The boy, intelligent and seemingly well-mannered, is shown to his room. Meanwhile, Miss Marquette is rewarded with a vampiric bite from the Count. Later, the Count listens as the Countess reads a frightening story to the child, though he is unable to determine why the boy was considered problematic. The boy, showing signs of unusual hairiness, transforms into a werewolf and attacks the Count and Countess, killing both. By morning, he has returned to human form, and Dudley arrives to retrieve him, revealing that the boy is his son.
