Devil Girl From Mars

Devil Girl from Mars concerns a female alien commander sent from Mars to acquire human males to replace their dying male population, thereby saving Martian civilization from extinction. When negotiation, then intimidation falls short, she must use force (both a raygun and a large robot) to obtain cooperation from a remote Scottish village, where she has landed her crippled flying saucer.
