A beautiful female extraterrestrial (Shirley Kilpatrick) – dressed in a skintight metallic suit with high heels, lipstick, and jet-propelled eyebrows – lands in the Sierra Madre mountains and goes around killing by touch and glowing mysteriously (thanks to her “deadly radium ray”).
Throw in a couple of wiseguy gangsters (Kenne Duncan and Ewing Brown), an alcoholic gun moll (Jeanne Tatum), a rich kidnapped heiress (Marilyn Harvey), and a lonely bachelor geologist (Robert Clarke) who lives in a remote cabin and talks to his dog, and you get the picture.
It turns out (after the geologist finally kills the She-Monster) that she was actually a peaceful emissary from the “Master of the Council of Planets of the Galaxy” with an invitation for Earth to join the Council.
She had killed only in self-defence. Oops!
Producer/director Ronnie Ashcroft used his wife, Lorraine, as Shirley Kilpatrick’s stunt double to keep expenses down (the entire movie cost just $18,000).
Released in the UK as The Mysterious Invader, the movie – which screened in many US cinemas as a double feature with Viking Women and the Sea Serpent – is listed among “The 100 Most Amusingly Bad Movies Ever Made” in The Official Razzie Movie Guide.
