Jesse James meets Frankenstein's Daughter

1966 directed by William Beaudine and starring (oh, why bother. It’s a no-name cast).

Jesse James arrives in town with guns ‘a-blazing, and meets up with the evil, sinister and no-good brain-obsessed grand-daughter of the infamous Dr. Frankenstein. Like her grandfather, the evil minx, who, for some reason is living in the Wild West, is carrying on “experiments” on innocent little immigrant children. Will Billy and Madame Frankenstein find love and happiness in the Old West, or will their evil shenanigans go topsy-turvy then fall to pieces in a mess of doom, gloom and…Kaboom!
