A couple (Ray Lovelock and Cristina Galbo) travelling along the English countryside stop to get directions from a pair of Ministry of Agriculture workers who are testing an experimental device designed to drive crop-damaging insects into killing each other. While they plan their next stop, a man who has been dead for several days attacks--to be followed shortly thereafter by a full-scale zombie invasion--which could very well be a result of the agriculturist's distribution of ultrasonic radiation. A macabre, atmospheric Spanish-Italian co-production featuring extremely convincing performances and a haunting score by Giuliano Sorgini. The second half of the film contains enough gut-munching gore scenes to satisfy most horror fans, leading to an unexpected and eerie finale.
George (Lovelock, AUTOPSY) is a hippie biker on his way to the countryside for a long weekend holiday. While stopping at a gas station, his motorcycle is accidentally hit by an attractive young girl named Edna (Galbo). The bike is rendered useless, so Edna offers him a ride, as long as they drop by her sister Katie's cottage first. The unlikely traveling companions get lost and stop at a farm for directions. There, George is greeted by a pair of employees from the experimental section of the Ministry of Agriculture as they test a new ultrasonic radiation device designed to drive parasites into killing each other. Meanwhile back at the car, Edna is violently pursued by a crazed man who appears to be already dead. After the agriculturists insure her it was merely the village loon, and the journey continues. Moments before they arrive at the cottage the same man who attacked Edna viciously murders Katie's husband. The police are quick to peg the wife as the primary suspect, and order George and Edna to remain in town during the investigation. As they lose faith in the fascist police force, the couple launches a secret investigation of their own. Suspecting the nearby agricultural experiments may be the cause of this morbid chain of events, they attempt to get more information from a local hospital. The result is a plethora of terrifying confrontations with zombies from the basement morgue--brought back from the dead to feast on the living.
