Two‑year‑old Penny, a sweet, soft little girl from the orphanage, always carries her tattered old green frog plush toy everywhere. Lucas brings her back to the manor for his brother Daniel, who’s trapped in severe depression and shut himself off from the world. Feisty and playful, Penny isn’t scared of the cold, brooding Daniel. She camps outside his locked study door. With a child’s innocent kindness, she slowly thaws his frozen heart. She blows on his hurts, shares cookies and scribbled drawings, and heals the tormented billionaire with her whole‑hearted love. Trouble and mean tricks from inside the family keep popping up, yet Penny defuses conflicts with her goodness. In the end, Daniel pulls himself out of his dark depression and truly becomes Penny’s dad. The whole Sterling family gets touched by the little girl’s warmth, finding love and happy togetherness.
