A strange man named Karl Rhamarevich dies shortly after discovering a way to become even more powerful in death through telekinesis. On the night of his burial in a crypt, Julie is to spend the night there as part of an initiation rite, supervised by two other girls. The crypt becomes a scene of horror as Raymar returns to life and deploys his horrifying telekinetic powers.

Ten years after a band of mercenaries first battled a vicious alien, the invisible creature from another world has returned to Earth — and this time, it’s drawn to the gang-ruled and ravaged city of Los Angeles. When it starts murdering drug dealers, detective-lieutenant Mike Harrigan and his police force set out to capture the creature, ignoring warnings from a mysterious government agent to stay away.

Dutch and his group of commandos are hired by the CIA to rescue downed airmen from guerillas in a Central American jungle. The mission goes well but as they return they find that something is hunting them. Nearly invisible, it blends in with the forest, taking trophies from the bodies of its victims as it goes along. Occasionally seeing through its eyes, the audience sees it is an intelligent alien hunter, hunting them for sport, killing them off one at a time.

Returning from a hunting trip in the forest, the Henderson family’s car hits an animal in the road. At first they fear it was a man, but when they examine the “body” they find it’s a “bigfoot”. They think it’s dead so they decide to take it home (there could be some money in this). As you guessed, it isn’t dead. Far from being the ferocious monster they fear “Harry” to be, he’s a friendly giant.
