Frankie Avalon and George Nader (that guy from "The Robot Monster") are a couple of wise-cracking| swingin' secret agents. Their enemy is Shirley Eaton as Su-Muru| who plans to remove all of the men who are currently in power and replace them with her army of women| most of who are shown in skimpy (for 1967) bikinis or mini skirts| and who can all perform complex tasks such as break a man's neck with their thighs. Avalon and Nader make "friends" with several members of Su-Maru's army| then invade with the local army and kill the rest of them.
