In this segment, Ari Daniel introduces us to a young woman and her years-long search for the man whose donated sperm was used in her conception. Kathleen LaBounty has thought long and hard about what fatherhood means, about the psychology of genetic relationships, and about the complicated emotions tied up in family, responsibility, and identity. Her persistence and determination brought her into strangely intimate contact with complete strangers, who had some surprising and unexpected reactions to her sudden appearance in their lives.
