Overview
From Beyond is a 1986 American science-fiction body horror film directed by Stuart Gordon, loosely based on the short story of the same name by H. P. Lovecraft. It was written by Dennis Paoli, Gordon and Brian Yuzna, and stars Jeffrey Combs, Barbara Crampton, Ken Foree and Ted Sorel.
From Beyond centers on a pair of scientists attempting to stimulate the pineal gland with a device called the Resonator, with the unforeseen result of their perceiving creatures from another dimension. The creatures drag the head scientist into their world, returning him as a grotesque shape-shifting monster that preys upon the others at the laboratory.
Plot
Scientist Dr. Edward Pretorius has developed the Resonator, a machine that allows whoever is within range to see beyond normal perceptible reality. His assistant, Dr. Crawford Tillinghast, activates the machine and sees strange creatures in the air. He is bitten by one of them. He notifies Pretorius about the machine's functionality. Pretorius, driven by lust for power and knowledge, turns the machine on and becomes mad with the feelings the Resonator causes. The Resonator malfunctions at full power, causing Crawford to panic and flee. When the police arrive, they find Pretorius decapitated, yet no blood. Crawford is arrested for murder.
Crawford is committed to a psychiatric ward, where he is treated by Dr. Katherine McMichaels. After Crawford gives his account of Pretorius' death, Katherine orders that Crawford undergo a CT scan, showing that Crawford's pineal gland is enlarged and growing. Convinced of Crawford's innocence, Katherine has him released to her custody, and takes him back to Pretorius' house and the Resonator. They are accompanied by Detective Bubba Brownlee, who investigated Pretorius' death.
