While on a family trip to Shelbyville, Marge is dismayed to see how Springfield residents are perceived as hicks in a production of "SONG OF SHELBYVILLE". At the next Springfield Cultural Activities Board meeting, Marge convinces the townspeople to fund a Frank Gehry designed concert hall. The opening night hustle and bustle is cut short as Beethoven's Fifth Symphony drives the uninterested townspeople away in droves which leads to the bankruptcy of the hall. The ever generous Mr. Burns assumes the debt of the hall and turns it into The Montgomery Burns State Prison. At first, the prison benefits the townsfolk by offering jobs to almost everyone (except Homer who fails his urine test due to a mix-up with Otto); however, when Mr. Burns pressures Chief Wiggum to increase capacity from 99% to 100% Homer finds himself imprisoned for kicking a can down the street 5 times in a row. Homer doesn't adjust to prison life well and becomes a snitch after accidentally ratting on Snake during a breakout. Homer enjoys the benefits of snitch life (plasma TV, cell phone, segway, a chance at a free pair of socks) until Fat Tony puts a mark on his head for selling out the mob. The angry prisoners fake a jail break and start a riot as they hunt Homer. As president of the Activities Board, Marge uses her concert hall key to sneak into the prison and convince Homer that snitching is wrong. National Guardsman swoop in at the last moment to save the cornered couple and Homer decides to use his snitch powers for good by.
