The first twenty minutes or so of this are quite entertaining. Who knew that "Blackie" (Chester Morris) was a dab hand at magic tricks? Well he takes his cabinet to a women's prison where he asks inmate "Dinah" (Constance Dowling) to have a go. Next thing, sirens are going off and there's no trace. "Insp. Farraday" (Richard Lane) and sidekick "Matthews" (Frank Sully) drag him in for questioning and we have some playful mischief around this magical device before, well it's soon not much use for anything but bonfire fodder. Meantime, there's a standard who robbed who and wants their share revenge... llegiu la resta.
