Calvin is the smallest guy in his high school, and a perfect target for Rozelle and her girl gang. His mother is dead, his father is long gone and his only remaining relative, his grandmother, is getting too sick to run her dry cleaning business. The only time Calvin feels in control is when he's working his yo-yo. When he takes up street performing, Rozelle demands a cut and insists on being his manager. To get media attention, she markets him as a yo-yo genius who can predict the future, dubbing him the 'Yo-Yo Prophet.' Calvin begins to believe his own hype, but as Gran's condition deteriorates, he realizes that it will take more than fame and adulation to keep his family intact.
