It's exactly what it sounds like. You're all a part of the cursed class 3, with one of you secretly being the dreaded extra. However, I'll be filling the role of the class 3 teacher, dodgeball legend Patches O'Houlihan. Solve a deadly mystery in a hostile environment that will spontaneously and 'accidently' kill you in wonderfully gruesome ways, all whilst the grizzled man hired to educate you throws wrenches at everyone with merry abandon and crude insults.
