In a banana republic, way south of the Texas border, a dumb-Dora American girl, Norma (Olive Borden), lets her ruby-red lips promise more than she is willing to deliver, and she finds herself a prisoner in a notorious dance-hall/brothel. But her American aviator boyfriend, Barry Blake (John Boles), is flying to her rescue. He does just that but, alas, they are quickly captured by a gang of outlaws. Possibly the many expensive pieces of jewelry she has gathered from the many male friends she has made along the way, including El Presidente, captured the outlaws' attention.

An insane scientist doing experimentation in glandular research becomes obsessed with transforming a female gorilla into a human...even though it costs human life.
