A year after her mom passed away, Julie plays one of her old CDs. Suddenly, three ghosts appear — the guys from the '90s band Sunset Curve!

When Julie starts singing again, the boys and her best friend Flynn encourage her to fight for a spot in the school music program.

Julie's performance makes a big splash, and the guys try to convince her to join Sunset Curve — but she'll have to come clean to Flynn first.

Flynn books Julie and the Phantoms to play at the school dance, Alex hangs out with his new crush, and the boys decide to teach an old friend a lesson.

Willie brings the guys to an exclusive club, where a powerful ghost magician asks them to be in his band. But he's got something up his sleeve.

Julie pairs up with Nick for a school performance and learns he broke up with Carrie. The band gets a new gig, but Julie's grounded for missing class.

Julie rehearses with Nick — while daydreaming about Luke. Alex wonders why Willie's been acting so weird. The band plays a party at Julie's house.

Julie meets Luke's parents and shares a touching song he wrote. Luke confides in Julie about Caleb and the band's "unfinished business."

Julie and the Phantoms get their dream gig at the Orpheum! But when Caleb interferes, Julie searches for the courage to perform on her own.
