Nishikido plays the 30-year-old salaryman Hongo Yuji, whose job in human resources had him laying off employees until he himself was laid off. With his family of four on the verge of collapse, he ends up taking in a Pomeranian puppy, which gets named Sky Tree due to the family living in a downtown area near the Tokyo Sky Tree tower. Raising the dog helps bring the family back together, resulting in a home drama full of laughter and tears.
