4th grader Sam Spitero is used to hanging out at home after school playing video games and listening to music. But when his mom gets a new job with late hours, he’s forced to switch his routine and go to an after-school program at the Boys & Girls Club—which he’s not happy about. He likes playing basketball in the gym, but the kids from across town pick on him because he’s short.

But when Sam joins the club’s new Hip-Hop Workshop, he makes friends with kids who share his same interest in music, and starts rapping under his new alias: Spit. The only problem is, he’s too nervous to rap in front of anyone!

As Spit and his friends prepare for the big Rap Royale talent show, they learn the steps to creating their own basketball-themed hip-hop song and performance from scratch. But after weeks of hard work and rehearsals, will Spit’s stage fright hold them back from winning the grand prize?
