Three black-clad agents — the Tigresses: Emily, Diana, and Barbara — battle the master criminal Garrick, who is after a secret formula, though their efforts are complicated by the fact that one’s boyfriend actually works for the evil villain. A maid who wants to become an agent herself provides some comic relief. A fairly entertaining 1960s spy film despite a limited budget and a sometimes silly story.

  Mildly recommended. Otto judiciously thinks this movie is OK.

Movie 546 for 2021.
