A teen joins his favorite classic rock band and tries to help them make a comeback. In the opener, Tripp Campbell (Logan Miller) wins a radio contest that includes dinner with his favorite band, Iron Weasel, and he lands a place in the band as their lead guitarist.
Tripp gets dumped by his girlfriend and writes a song about the experience, called "I Wanna Punch Stuff." Later, Tripp surprises his bandmates with a visit from a professional mixed-martial-arts fighter who holds a grudge against the band.
Tripp takes Arlene, an annoying classmate, on a date after he learns that her dad is a record producer. Unfortunately, Tripp gives her an Iron Weasel demo with the song "Annoying Arlene" on it, so the guys try to swipe the CD before anyone listens to it.
Tripp tries to persuade the band's former manager to represent them once again, but their meeting ends in disaster. As a last resort, Derek and Tripp perform a magic show for the manager to get him to reconsider.
Tripp attempts to persuade his wealthy girlfriend to give up her lavish lifestyle. But to do so would mean canceling her elaborate 16th-birthday party, at which Iron Weasel was going to get paid to play.
The band star in their own reality series, but when the ratings plunge the guys fabricate some infighting to spike viewership. Unfortunately, the fake quarrels become real and the guys are soon competing with one another for a chance to record a solo album.
