Things suck for Stanley Coopersmith. He's a welfare student for a Military School and is basically at the bottom of the pecking order. One day it all changes when he is given a punishment duty of cleaning the academy's chapel's basement. There he discovers belongings of late Father Esteban Lorenzo, who was executed for Satanism in the 16th century. Coopersmith then starts studying Lorenzo's material and later uses his newly gained power to turn the tables against his tormentors.

Tropes used in Evilspeak include:
