Return Of The Living Dead 3
Curt's father is Col. John Reynolds (Kent McCord), a scientist working on a top-secret project at a nearby military compound. When Curt steals his dad's security pass and sneaks Julie into the base, they discover that the project involves bringing corpses back to life using the powerful gas Trioxin, responsible for events in the previous films. The military hopes to use the mindless, flesh-consuming zombies as weapons, but the experiment goes gruesomely awry.
