Halbert is a sad young lad trying to tend to an ailing ficus plant. Despite his vigorous watering regimen, the ficus will not grow. One day, heavy metal music drifts over his neighbor's fence, causing a new leaf to sprout from the sapling. Halbert quickly picks up the music as a new passion. His mother, however, wants him to stop wasting time on his ever-rotating wheel of hobbies, and to focus on his future. Determined, Halbert commits to the metal music with the aid of his neighbor, Abby, and is not only able to make his ficus flourish, but himself as well.
