In the troubled mountain town of Lake Leer, Colorado, a bullied high schooler by the name of Kora Lynch becomes the latest in a long line of local killers when she ends up drowning herself to escape her persecution. Rescued from herself by a goddess of mysterious whims known only as Ira, Kora is offered a choice - to die alone and wither away forever, or to become a "Vision of Vengeance" and do away with all who bring harm. Choosing to become Ira's latest slasher, Kora is given a weathered kabuki mask and the gift to see anyone's every sin with a glance. Eager to seek revenge on those who drove her to die in the first place, Kora takes the name of "Karma" and begins slaughtering her classmates in a misguided attempt at justice, disguising her descent in a gruesome homage to her favorite slasher movies. As she further disconnects from the real world and loses grip of her moral compass, the woman that broke her rallies the town into defiance, and the ensuing conflict tugs all of Lake Leer into irreversible carnage.
