"When it comes to education – the devil is in the details - quite literally! Bart gets re-zoned to Hellementary School! And the Springfield schools get some... interesting... transfer students. Old Scratch, the devil himself, comes to put the barter back in charter school, but will you trade your soul for an elementary school education? Can the Simpsons out-bargain the Prince of Darkness? Or will an eternity of damnation be their fate?"
