Evils of the Night is a low-budget sci-fi horror movie released in 1985. The movie opens with a group of teenagers who are out camping in the woods. They are all college students who are looking forward to having a weekend of debauchery. However, their plans are quickly halted when they are kidnapped by a group of auto mechanics who take them to a remote location.
The teens soon realize that they are not the only ones being held captive. There are other people, including elderly men and women, who are also being kept at the same location. The captives soon learn that they are being used as a source of blood by a group of aliens who are trying to prolong their own lives.
The aliens are an advanced race who have come to Earth to study humans and find a way to extend their own lifespans. They have been working with the auto mechanics, who have been kidnapping people for them in exchange for advanced technology.
