"The Rocker," aka Robert "Fish" Fishman, was the drummer for an '80s hair band. He was living the rock 'n' roll dream until he was kicked out of the group. Twenty years later, the desperate rocker joins his nephew's band, "A.D.D.," finally reclaiming the rock-god throne he's always thought he deserved--while taking his much younger band mates along for the ride of their lives.
