Return of the Living Dead 3

Return of the Living Dead 3 is a 1993 horror comedy film directed by Brian Yuzna and written by John Penney. It is the third film in the Return of the Living Dead film series, following Return of the Living Dead Part II (1988). Plot Five years after the events of the previous film, Curt Reynolds steals his father's security key card, and he and his girlfriend, Julie Walker, explore the military base where his father works. They observe Curt's father, Colonel John Reynolds, Col. Peck and Lt. Col. Sinclair overseeing an experiment with a deceased body. The corpse is exposed to 2-4-5 Trioxin gas, which re-animates the corpse into a zombie. The military hopes to use zombies in combat. However, they are impossible to control as their hunger for human brains causes them to constantly attack. To deter the zombies' vicious nature, Sinclair suggests permanently attaching the zombies to exoskeletons that will immobilize them when they are not in battle. Reynolds prefers a method referred to as "paretic infusion", which involves firing a chemical projectile into the forehead of the zombie. This causes an endothermic reaction, freezing the zombie's brain and temporarily immobilizing it.
