Painfully shy, high school student Tara (Debby Ryan) has an awesome secret - she is "Radio Rebel". When Tara puts on her headset and does her daily podcast, she becomes a confident, inspiring, anonymous voice on the airwaves.

When her stepfather, the owner and producer of Slam radio, finds out that Tara is Radio Rebel, Tara gets to move from her bedroom to a sound studio to do live shows for Slam.

Everything is going swimmingly until Principal Moreno, whose only goal in life seems to be to destroy others, cancels Prom Night and all the students blame Rebel.
