After Grace Bennett the delivery driver helps Abigail Sterling, Abigail secretly sets Grace up with her father, Donovan Sterling, Chairman of Sterling Group. Broke and burdened by her deadbeat son Trevor Bennett stealing her wages, Grace initially refuses. But when her mother-in-law tries forcing her to marry the scumbag Mickey for a bride price, and Trevor racks up a $20,000 debt at an underground bank, a devastated Grace agrees to the date. Donovan disguises himself as a security guard to find a maternal figure for Abigail, whose violin playing has suffered without a mother's love. Grace accepts his humble status, and Donovan admires her virtue, leading to a flash marriage that very day. When Grace's family locks her up to force the marriage to Mickey, Trevor finally shows some conscience and sneaks her out. Mickey corners her, but Donovan rescues her and brings her to a cozy rental to start over. Later, Trevor's girlfriend indirectly causes Granny's death, drains his cash from selling her house, and leaves him homeless. Donovan helps Trevor turn his life around while the girlfriend faces justice. Empowered by Grace's love, Abigail becomes a genius violinist. Ultimately, Grace discovers Donovan's true identity, and they live happily ever after.
