Lizabeth Virginia Scott, educated at Marywood University and living til ripe old age of 93, played a mercurial materialistic, keep up with the Jones character who had 100,000 dollars inadvertently dropped into the car of her and her husband involving a high speed chase scene with intended recipient of the big bucks.
