Moore plays a would-be actress who couldn't act her way out of phone booth with the door open. When she fails miserably with three lines, the director (Haas) replaces her. An angry and deeply disturbed woman, she decides to destroy him and sets him up for blackmail.
After suckering Walter Darman (Haas) into giving her a ride home, Sherry (Moore) slips him a mickey. The next morning he has lipstick on his face and shirt, and Moore is acting as if they had a night of fun. And she makes sure her friend (Lance Fuller) stops by to see Darman there. All part of the plan.
Sherry later claims to be pregnant and wants $50,000. Darman is sure she is lying, that nothing happened, but she calls and visits his office frequently, putting on the pressure.
Hugo Haas and Cleo Moore made I think seven films together, B movies, and made a good team. Haas in his native Czechoslovakia wa a well-known actor until he had to flee the Nazis. He continued acting in the states but also became a writer and director, specializing in these B noirs.
Cleo, a blond sexpot in the Monroe tradition, has the street-wise femme fatale down and looks fantastic. Married at one time to Huey Long's son, she actually ran for Governor of Louisiana in 1956 (a publicity stunt).
Moore quit movies in 1961 when she married a multimillionaire. She certainly was a better actress than the character she played. Sadly, she died young and didn't live to see the cult status she achieved in the '80s, which continues.
All in all, like other Haas films, entertaining.
