China Jones is an Irish private eye who is working in the Far East. His next call involves a fortune cookie with a message inside telling Jones that there's a prisoner in a Chinese bakery, so he decides to investigate. His first stop is a bar owned by Limey Louie, an ex-convict who blames Jones for sending him to prison. Louie is disguised as a widow who is grieving for her husband's alleged death, and uses this to make a fool out of Jones. Additionally, China Jones encounters Charlie Chung and thinks he's also working the same case hoping to get the supposed reward (although, towards the end, Charlie Chung explains that he was not a detective, he's a laundry man, and that the money he was talking about was Jones' laundry bill). Jones ends up as a "prisoner" in a Chinese laundry to pay off said bill speaking to the audience in "Chinese" with subtitles, "Help! - I'm being held prisoner in a Chinese Laundry!".
When this cartoon aired on Nickelodeon in the 1990s, the end where China Jones (Daffy) is imprisoned in Charlie Chung' (Porky's) laundromat, loudly ranting, "Help! I'm being held prisoner in a Chinese laundry!" in faux Chinese was cut, ending instead on Charlie Chung brandishing a club and telling China Jones, "Confucious also say, 'B-better you press shirt than press luck'."
Due to the rampant Chinese stereotyping, this short has rarely, if ever, aired on American television (with the 1990s being the last time it was shown, as mentioned above), nor has it been seen on any modern home media (read: VHS, DVD, and Blu-Ray) releases.
