Ms. 45, also known as Angel of Vengeance, is a 1981 American low-budget exploitation film directed by Abel Ferrara and starring Zoë Tamerlis Lund. Inspired by films such as 1973's Thriller - en grym film and 1974's Death Wish, the film is a rape and revenge story about Thana, a mute woman who becomes a misandristic spree killer (not strictly a vigilante) after she is raped twice in one day when going home from work.
