After an all-night binge, carnival owner Leo Torbey (Norman Lloyd) discovers he has purchased a trained monkey, whom Torbey's wife, Carol (Nita Talbot), despises at first sight. What Leo doesn't know -- at least at first -- is that his monkey, named Maria, is not a monkey at all, but instead a human female dwarf (Venus DeMars). And what nobody knows, until it is too late, is that Maria has fallen hopelessly in love with Leo...and that she has an insatiable thirst for vengeance. ~ Hal Erickson, Rovi
