i suppose that that the majority of quota quickies were crime films because this limited the size of the cast and the number of sets required.This is a mystery drama with a difference.Not only is the story a mystery drama the actual film is a mystery as it is totally unfathomable.At the beginning of the film Hugh Williams is attacked so that someone can use his costume for a masked ball.Why the thief didn't hire his own costume is not explained.At the ball a shield is stolen and Jane Baxter is abducted.Why she is abducted is never made clear.The shield has been stolen for a mad astronomer who falls out with the crooks.Don't expect me to explain why,and so on.Maybe the original 79 minute version would explain all.Till then we will be kept guessing.
