This is a modern American wealthy-family paternity-reunion short drama. Its core elements are a three-year-old cute baby searching for her father, wealthy-family recognition, father-daughter redemption, a deceased mother's last wish, family interest struggles, and the reopening of an old case. Three-year-old Mia Bennett, after her mother Lena's death, arrives alone in a yellow raincoat on a stormy night at Whitmore Estate in New York. Holding an old rabbit and a childish "Daddy IOU," she finds Adrian Whitmore and demands "three years of milk money." Her appearance shatters the family's peaceful life. Mia brings Lena's obstetric bills, birth photos, and a crescent moon pendant, and knows Adrian's private habits. After two paternity tests, she is confirmed as Adrian's biological daughter and gradually enters the Whitmore family. Her arrival reopens the old wound concerning Lena. The family had believed Lena took five million dollars and left. A new investigation reveals that funds from a Whitmore Foundation account entered an account under Lena's name but were split into four transfers and moved away within three minutes. Lena's account was only a transit tool. Ethan Whitmore reinvestigates. Lena's recordings prove she tried to seek help, and her messages were deleted. Evidence points toward Claire and Daniel Whitmore Jr. Claire admits she showed Lena a "parental rights waiver" allegedly signed by Adrian.
