On a night when the roads are blocked, eight siblings support their mother.
Outside, a fierce storm rages with howling winds and driving rain. The road to the maternity clinic has been cut off by a landslide, and the mother's cries of labor echo through the house. Having steeled their resolve, the family chooses to perform a water birth in their own bathroom. Amidst the rising steam, beside the bathtub filled with lukewarm water, stand the quintuplets and triplets who used to do nothing but bicker. As the eldest son, Yuto, gives directions and the eldest daughter, Yuna, grips her mother's hand, you—only two years old—watch over your mother's feet with your tiny hands. Facing the miracle of birth, the bonds of a scattered family are about to be tested and forged into one.
