In a slanted dwelling beyond the outskirts of a drought-ridden town, a close family accepts an impossible blessing and names their only son Sailboat. Sailboat stirs new love and hope in his family, who forge a simple but proud life in the American Southwest. One afternoon Sailboat brings home something more, a "little guitar," and from this moment on the boy and his ukulele are inseparable. When his gravely ill grandmother instructs him to write a song for her, Sailboat meanders through adversity to deliver the unimaginable - the greatest song ever written. Will the song breathe one final miracle, or will it reveal a hapless twist of fate that will return Sailboat's family to a house held up by a stick, a car without doors, an unchanging wardrobe, and a friend who can't blink?
