For Marty, School Days were the worst days of his life... When the alumni of an all-American high school make a trip to attend a class reunion, they reconnect with their pasts in ways more bloody and fatal than they could possibly imagine in the 80s slasher classic 'Slaughter High'. On arrival, they discover the school shuttered and in disrepair, as if the reunion were just a ruse to drag them back. Still, the old pupils decide to break in and celebrate anyway. A deadly error considering that Marty, the nerd whose teenage life they made a living hell, is lurking in the dank, dark corridors, waiting to bring fear, torment and slicing, dicing murder to each and every one of them.
