Released in the U.S. as It Takes a Thief, this U.K. film has Jayne Mansfield as Billie, who acts demure by day but leads a gang of robbers at night. One of their old members, Maxton, went to jail and they think he knows where the big score they made got hidden. They take his son, despite the ending which lets everyone know that the money had been found three years ago.
Director John Gilling has a pretty good resume of films in his history, like The Flesh and the Fiends, The Plague of the Zombies and The Mummy’s Shroud. This isn’t the best interesting movie you’ll see, but as always, Mansfield rises above the material.
