"Earthling astronauts crash land on exotic Venus and find themselves assaulted by terrible monsters in this sci-fi adventure. Fortunately, the planet's other residents, beautiful women, come to their aid and help them to return home. Much of the film is comprised of scenes from two other films, Voyage to a Prehistoric Planet and a Russian film Planeta Bur. The film is the directorial debut of Peter Bogdanovich."
