The weekend invitation seemed innocent enough until three college beauties find they've RSVP'd to 48 hours of Hell. The NIGHTMARE WEEKEND starts when a professor's evil assistant lures the girls into a bizarre scheme to perform hideous experiments. Using a brain implant that turns humans into gruesome zombies, she transforms her victims-and their unsuspecting dates-into clawing, dripping horrors with murder on their minds. The zombie creatures relentlessly pursue the professor's innocent daughter, but her screams go unheard. Only a benevolent computer can halt the terror-but will there be time? When insanity joins forces with technology-that's when the horror of NIGHTMARE WEEKEND begins.
