In a slanted dwelling beyond the outskirts of a drought-ridden town, a close Hispanic family accept an impossible blessing and name their only son Sailboat. Sailboat stirs new love and hope in his family who forge a simple but proud life in the deep South West of America, but one afternoon he brings home something more: a "little guitar". From this moment, Sailboat and his ukulele are inseparable, and 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 reveal a hapless twist of fate that will return his family to a house held up by a "stick", a car without doors, an unchanging wardrobe, and a friend who can't blink?...
