Evilspeak

Evilspeak is a 1981 American horror film directed by Eric Weston, who co-wrote it with Joseph Garofalo. Clint Howard plays Stanley Coopersmith, a cadet at a military academy who is bullied by classmates and mistreated by instructors. After finding a Black Mass book once owned by the medieval Satanist Father Lorenzo Esteban, Stanley uses a computer to translate it and summon demons and spells for revenge. The movie was classified as a "video nasty" and banned in the United Kingdom during the 1980s.

The plot begins in the 16th century, when a priest tells Esteban and his followers they are exiled to America and will be denied God’s grace unless they renounce Satan. In the present, Stanley is an orphan cadet at West Andover military academy. While cleaning a church cellar as punishment, he discovers a hidden room containing Esteban’s books on black magic. Using his computer skills, Stanley translates one from Latin into English, finding a diary with Black Mass rituals and a promise from Esteban: "I will return."

The next day, classmates unplug Stanley’s alarm and knot his clothes, making him late. His teacher sends him to Colonel Kincaid, the headmaster. In Kincaid’s office, Stanley accidentally leaves the diary on secretary Miss Friedemeyer’s desk; she hides it. While Stanley cleans a pigsty, she tries to pry jewels from the book’s cover, prompting pigs to attack her. Back in his dorm, Stanley finds his belongings scattered and assumes his classmates stole the diary, but they deny it. He researches Satanism in the computer lab but runs out of time.

Stanley sets up stolen computer equipment in the cellar and checks the ritual’s requirements. The computer says he still needs blood and a consecrated host. Reverend Jameson nearly catches him and sends him to the mess. Arriving late, Stanley befriends the cook, who feeds him and shows him newborn puppies. Stanley takes the runt, names it Fred, and hides it in the cellar. He steals a host from the church and attempts the ritual, but classmates in pig-faced robes knock him unconscious. After they leave, the computer says the ritual is incomplete. Stanley accidentally wakes drunken caretaker Sarge, who attacks him; an unseen force twists Sarge’s head around, breaking his neck. Stanley finds a catacomb with Esteban’s crypt and hides Sarge’s body.
