On the first floor of the Lafayette Apartments, facing demolition, Eve runs ‘Moon Dumpling’. One cold winter day, she takes in Rex, a handsome flower-picking vagrant. In truth, Rex is the building's sole heir and a notorious troublemaker in Manhattan high society! For some reason, he pretends to be a flower-picking vagrant, stays at ‘Moon Dumpling,’ and helps Eve. Eve is shaken by Rex, who dashes around calling her Noona. What will become of their relationship?
