There's this white guy holding up stores in San Francisco's Chinatown for objets d'art. He prepares by learning Chinese phrases for tourists from a phonograph record. After he steals a valuable vase by the clever ploy of shooting the clerk he sees a young woman in the next room phoning the police, so he shoots her, then gets on the phone and tells the operator, in Chinese, "a robbery at Wing's store, call the police."
Why does he need to learn Chinese to perform stickups in Chinatown? Why does he report the crime to the telephone operator? Why does he do it in Chinese? Did the language course really include the Chinese for "a robbery at Wing's store, call the police"?
If you think the film is going to answer these questions, you are going to be disappointed. And this is only the first few minutes. Nearly all the actions of police and crook throughout the remainder are equally illogical or counterproductive. Moreover the film was so low-budget that long stretches are a silent movie with voice-over narration.
In other words, this could well have served as Mystery Science Theater 3000 fodder. Since it didn't, why might you want to watch it? Old footage of Chinatown and other San Francisco neighborhoods. Brief appearances by two of Charlie Chan's number one (or two or three) sons, Victor Sen Yung and Benson Fong. You might want to laugh, of gag, at Hollywood stereotypes, both positive and negative, of Chinese Americans of that era. There's the usual pretty young Chinese American actress born fifty years too soon. The biggest surprise is the bad guy being played by Hurd Hatfield, just four years removed from the title role in MGM's The Picture of Dorian Gray. Hatfield never again attained Hollywood leading man status, but had a long and successful career. How he sank, even temporarily, to this low ebb is the film's real mystery.
But the main reason to watch is if you're into "so bad it's almost surrealistic." If you're an Ed Wood fan you'll probably enjoy this film.
