This episode in the Chan series features skimpy sets - not rare in the later Chans - and a weak role for the usually entertaining Mantan Moreland, but some Chan is better than none. Roland Winters does a perfectly serviceable job as Charlie - lacking the warmth of Warner Oland, but also lacking the harshness of Sidney Toler in his father/son interactions. The plot is pedestrian, but the series is about Charlie and assistants, not the stories, so a less than perfect plot is OK. This movie lacks the beautiful women in gowns we often get in Chans, and not much of a love affair, so some of the classic Chan features are missing. By this late time, they were spending very little money on the series, and milking it for the value of the franchise. One can imagine that it was a perfectly good way to spend an hour on a Saturday in post-war America.
I noticed that after crediting Roland Winters and one woman actress, Mantan Moreland and Victor Sen Young came next. In spite of the fact that a white man was playing Chan, clearly a black man and a Chinese man came next in popularity with audiences. For some reason, this fact is never credited. The theme of racist America is just to popular to be spoiled by such facts.
