During their sophomore year, John, the introverted momma's boy, showcases his musical genius in a homecoming talent show that changes both their lives forever. John's romantic crooning earns him the nickname "Loverboy." As his R&B career begins, he asks Darin to tag along as his manager. Darin wants no part in the music scene and has big dreams of his own, but when he suffers a season-ending football injury, he finally agrees to hop on the "Loverboy" bandwagon. The two set out to turn John into an R&B superstar. For Darin, dealing with John's rising fame and fortune proves a difficult challenge. The more the two adapt to the dangerous celebrity lifestyle of big-time money, fast women, and recreational drugs, the harder it gets for both of them to "just say no!"
