High schooler Julie (Madison Reyes) lost her passion for music after her mom died last year. But when the ghosts of three dreamy musicians (Charlie Gillespie, Owen Patrick Joyner, Jeremy Shada) from 1995 suddenly appear in her mom’s old music studio, Julie feels her own inner spirit beginning to reawaken, and she's inspired to start singing and writing songs again. As their friendship with Julie grows, the boys convince her to create a new band together: Julie and the Phantoms.
