Those hellish little green imps from Ghoulies return in this gory horror comedy. This time the trouble begins when the demonettes are purloined by a priest who wants to kill them. Unfortunately, they escape and end up hiding out in a nearly bankrupt carnival haunted house. With the Ghoulies there, soon the place becomes a thriving attraction and people flock to see it. It's great until the blood starts flowing all over the fun-house floor.
