Atom Age Vampire (1960)

You'll gasp with Horror...

When a singer (Susanne Loret) is horribly disfigured in a car accident, a scientist (Alberto Lupo) develops a treatment which can restore her beauty by injecting her with a special serum. While performing the procedure, however, he falls in love with her. As the treatment begins to fail, he determines to save her appearance, regardless of how many women he must kill for her sake.
