Plot
Emilia-Romagna, Italy, early 1970s. A UNESCO agent discovers that blood is contained in a bottle of wine produced by a well-known Italian winery. Meanwhile, Alfiero picks up several people discarded by society — a prostitute, a gypsy girl, a drunkard, and two hippie hitchhikers — and delivers them to the mansion of Dr. Antonio Genovese and his wife. The guests note the presence of a strange mechanical robot. One by one the guests disappear. Finally the hitchhikers make it to the mansion's basement, where they witness the robot draining the prostitute of her blood. Genovese's wife is revealed as the mastermind: Genovese, at his wife's insistence, has created a robot to suck the blood from the bodies of "worthless" humans; they package the blood in wine bottles and export it for profit to "wherever there are wars, or injured people."The UNESCO agent, having followed clues from the winery, arrives to search the mansion. He shoots Alfiero; Genovese's wife is killed by the robot; and the hitchhikers are rescued.
