Todd and the Book of Pure Evil (2010) A stoner metalhead named Todd Smith, his crushee Jenny, his best friend Curtis, and the geeky Hannah, search their high school for a mayhem-causing Satanic spell book, while being opposed by Atticus, the evil guidance councillor.
High school is hard enough without hell intervening. Thankfully, at Crowley High, Todd Smith is the last line of defense between his fellow students and the end of the world as they know it. His life changes one day when he happens upon a publication called "The Book of Pure Evil" and discovers its powers to make one's deepest, darkest desires come true ... like when he turns himself into a guitar god to impress his dream girl, Jenny. But the wish fulfillment comes with a horrifying cost, and when the book preys upon the weaknesses of other students, it's Todd's job -- whether he likes it or not -- to save the day.
