A young woman with a slave's heart and a little girl's soul leaves work one afternoon. She's both excited and nervous as she heads to the home of her Sir, a man who has also captured the heart of the little girl inside. That little girl is thoroughly devoted to the man she calls "Daddy". Even when she finds herself in trouble with her Daddy, and must then endure his punishment, her devotion never fails. As she suffers under her Daddy's hand, the slave-heart inside of her emerges, and she experiences the most wonderous joining of two distinctly different parts of her as they suddenly become one.
