This 1978 production of Unsichtbare Gegner bears no relationship with the 1933 thriller having the same name. Instead, it is a highly symbolic and experimental work by the Austrian avant-garde director Valerie Export. The faint storyline concerns the effects of a mysterious ray being beamed from outer space by beings known as the Hyksos, who are using it to direct the activities of people in order to take over the world. A photographer and her boyfriend are apparently the only ones in the city of Vienna who notice that something is not quite right.
