Lee (Ng Cho-fan), who is the retired jewel thief the Black Cat Burglar, is suspected by the police in a string of burglaries. While fleeing from the police's search, he realises he can only prove his innocence by catching the new Cat in the act. Meanwhile, he is romantically caught in between a young girl from overseas and his goddaughter. As a Cantonese ripoff of Hitchcock's To Catch a Thief (1955), this remake does not have the beautiful scenery from the French Riviera but is full of economical wonders. Director Wong Hang employs westernised filmmaking troops to enhance the film, making it outstanding from other Cantonese films of the same time. From high society gatherings to a hide-and-seek in a masquerade, the film demonstrates not only an elegant style but the versatility and adaptability of Cantonese films. Unlike Cary Grant, Ng Cho-fan manifests himself with a mysterious and artistic aura.
