A group of unsuspecting campers are faced with a threat from which no amount of bug spray can protect them in this sci-fi/horror thriller. An alien spacecraft crash-lands in a state park near a lake, and several hungry mosquitoes feed on the blood of the deceased spacemen. They soon mutate to many times their normal size, and Megan (Rachel Loiselle), a biology student, and her boyfriend Ray (Tim Lovelace), are startled when a bug crashes into their windshield -- a mosquito the size of a bald eagle. Megan and Ray soon join forces with Parks (Ron Asheton), the bumbling park ranger; Earl (Gunnar Hansen), a survivalist with a criminal past; and his pal Junior (Mike Hard), to do battle with the swarm of ever-expanding bugs. Rock fans note: Ron Asheton was guitarist with legendary proto-punks Iggy and the Stooges and penned a new song for the soundtrack, while Mike Hard was the lead singer with the group The God Bullies.
