A young mother holds her newborn son and sings him a song of endearment. As he grows older, he becomes an active two-year-old, a balky teenager, and an adult. Throughout, the mother coddles the son while he sleeps and sings him the same song. When she grows old and becomes sick, it's the son's turn to hold her and sing it to her; just as he now does with his own baby. This simple and touching story is about the enduring nature of a parent's love and how it spans the generations.
