Debby Ryan gets ready to take over the airwaves in this new still from Radio Rebel.

In the upcoming DCOM, the 18-year-old actress plays Tara Adams, an introverted high school junior who can’t bring herself to speak in class — and especially when the newly-popular rocker, Gavin (Adam DiMarco), is in her midst. Tara can’t imagine anything more intimidating than when her drama teacher teams her in class with Gavin and his prom date, the school’s cliquish queen bee, Stacy (Merritt Patterson).

Her shyness at school notwithstanding, alone in her room at home, Tara casts herself as Radio Rebel and, as host of a nightly podcast, showcases her passion for music and self-expression and her message to abandon cliques and celebrate each other’s differences.

Radio Rebel quickly gains fans on campus — especially when her show lands on a big, local radio station — much to the chagrin of the school’s principal who considers Radio Rebel and her message to be in clear defiance of the school’s “anti-distraction policy.” Meanwhile, Gavin raves about the mysterious host and her taste in music but still, shy Tara – now oddly jealous of her alter-ego – can barely finish a sentence in front of him.

As students clamor to learn the identity of Radio Rebel and the show’s popularity extends across Seattle, Tara’s two worlds begin to collide, reaching an apex when Radio Rebel is nominated prom-queen and the school, in turn, bans prom, causing a backlash from her fans. Now, Tara wrestles with two even bolder moves — organizing an alternative to the prom and revealing that she is Radio Rebel.

Radio Rebel will premiere Friday, February 17th @ 8PM ET/PT on Disney Channel.
