Nightmare Weekend

In the 1986 horror B-movie "Nightmare Weekend," three college females are enlisted for an experiment that supposedly improves behavior by a woman of dubious morality, led by professor Linda (Andrea Thompson). The project's assistant, Julie Clingstone (Debbie Laster), manipulates the computer program to warp people's minds and turn them into murderous weapons. As part of her twisted plan, Julie subjects three young college girls - Jessica Brake (Debra Hunter), Ken's love interest is mentioned but not a major character, Julie's assistant Dave (Robert John Burke) - to the machine's weird effects, leading to freakish and sexy hijinks over the course of the weekend.
