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.

This is a film that celebrates the moral function of art. Sun Ma Si-tsang, at once a master Cantonese opera actor and a talented comedian, showcases an oft-overlooked style of singing, presenting it as an inspirational force that saves life and betters relationships. He plays the titled character, who doesn't operate a boat and is nowhere near bodies of water, but an artist specialising in the Dragon Boat style of music. Forced to perform on the streets to make a living, he ventures into situations manifesting the many societal problems that plague Hong Kong, inspiring and elevating common folks with his artistry. He stars alongside Leung Sing-por in a classic animation of comedy partnership, generating laughter from the interactions between players of contrasting body types.

This script was adapted from a Rediffusion Radio airwave novel, written by Lang Wun and read on-air by his wife Ngai Mun. Ngai Mun also acted in this film. Wang (Cheung Ying) worked himself to an early death. His wife Ching (Hung Sin Nui) raised their three children all by herself. Eldest son Kei (also played by Cheung Ying) was spoiled and grew up to be a robber. Middle child, daughter Ching-han, is materialistic and vain, and is later killed by Kei. Youngest son Leung (Yeung Fan) is diligent and ambitious, a great comfort to Ching. Hung Sin Nui played Ching from a young to an elderly woman, showing off her practiced, perfect acting skills. Chun Kim’s detailed portrayal of the relationship between the two generations set the stage for his later work Parents’ Hearts (1955).
