When Homer is secretly videotaped complaining about his family during an episode if Taxicab Conversations, they send him off to a rock and roll fantasy camp so he can regroup and try to live his dream.
The family gets very angry at Homer after he rants about how annoying his family can be on public television and as the tension builds up, they realize that he is stressed out and sad that he could never realize his childhood dream of becoming a rockstar, so they send him to The Rolling Stones Rock N' Roll Fantasy Camp, where Homer, Otto, Lenny, Carl and other Springfieldians learn to play guitar, dress, sing, evade groupies and show off like rock stars.
Homer is disappointed when camp is over, so The Rolling Stones offer him to help them with their concert. Homer even receives an "All Access" pass, and feels like he has all access, and helps himself at the Squeaky-Voiced Teen's refreshment counter and the ladies' room.
However, Homer believes that he will be performing with them and is disappointed when he discovers he was just there to test the microphone. Homer then breaks free from his testing duties and starts playing guitar and singing. The Rolling Stones quickly get frustrated that Homer is stealing their show so they try to stop him by chasing him on-stage in a car shaped like a devil's head that spews fire. It ends very badly when their car crashes into the fans.
To apologize, they invite him to play with them on their next gig but Homer kindly declines the offer, as he already has a band of his own: his family. They give the devil's head as something to remember them by, and Homer uses it to drop Bart off at school in the bus zone and burn the pants off Principal Skinner.
