Fernando Rey is a wheelchair-bound professor who has developed a formula that can heal scar tissue. When he alights upon the badly disfigured "Norma" (Lisa Gaye) he injects her with his serum with almost miraculous results, which he proceeds to display to his peers and friends. Unfortunately, the serum begins to wear off and "Norma" - who had only recently escaped from a mental institution determines to exact revenge on the doctor and his assistant "Alma". The acting and dialogue are competent, but the pace is shockingly slow - far too many development scenes and far too little actually happens to keep the attention until the last ten minutes when "Norma" goes on a bit of a murderous spree. Although the dubbing is not bad, and it looks like some of it has been re-shot in English; it still struggles to make much headway leaving more blemishes on the story than his serum could really ever hope to cure.
