Shy teenager Tara Adams attends Lincoln Bay High in
Seattle and secretly works as the city's most popular radio DJ, "Radio Rebel", unbeknownst to her friends Audrey, Larry, and Barry. Tara's crush Gavin and his friend Gabe are in a band called The G's, and hope to perform at prom. Tara's stepfather Rob, who runs the radio station SlamFM, asks Tara about Radio Rebel in an attempt to bond with her. Her identity as Radio Rebel is subsequently discovered by Rob and her mother Delilah, and Rob invites her to host her show at SlamFM. Tara has doubts, but is inspired by another radio host, DJ Cami Q, whom she befriends. Audrey and Tara's friendship becomes strained as Tara continually declines invitations to spend time together; Tara eventually reveals her identity to Audrey. Gavin leaves a copy of his band's demo in the drama room, which Tara takes and plays on her next show, encouraging students to start spontaneously dancing. Principal Moreno, feeling threatened by Radio Rebel's anti-authority message, threatens to expel anyone caught listening to the show. Cami Q arrives at school with a recording of Radio Rebel stating that she is taking back the music that Moreno took away. Moreno begins disciplining students who withhold information about Radio Rebel's identity. Eventually, Radio Rebel is nominated for prom queen, but Tara refuses to accept the crown to preserve her anonymity. When Tara does not reveal herself, Moreno cancels the prom. With Cami's help, Tara and Audrey sneak into SlamFM and broadcast a call for students to express their true feelings. Tara then announces plans to hold a "
Morp" (prom spelled backwards). Tara's rival Stacy begins to suspect that Tara is Radio Rebel and holds a house party at the same time as Radio Rebel's next broadcast. Tara attends while Delilah and Cami host the show using pre-recorded voice snippets. Stacy's friend Kim infiltrates SlamFM and obtains evidence that Tara is Radio Rebel. At school, Gavin quits The G's, fed up with Gabe's egotistical personality. Stacy locks Tara in the janitor's closet and threatens to expose her. Tara agrees to support Stacy's prom queen campaign in exchange for keeping her secret. Gavin finds out and rebuffs Stacy's invitation to the Morp. At the Morp, Moreno keeps watch for Radio Rebel as Cami announces the prom queen. When Radio Rebel wins, Tara overcomes her fears and reveals herself. When Moreno moves to expel her, other students come forward, each declaring "I am Radio Rebel". Unable to expel the entire student body, Moreno reluctantly backs down. Tara hands Stacy the crown, ending their rivalry, and Gavin performs a song dedicated to Tara. ==Cast==
