Chinese princess is murdered on her arrival in America, and the funds she was going to use to buy fighter planes for her brother (obviously meant to be Chiang Kai-Shek) goes missing. Charlie Chan has to discover who is the killer.

Decent enough effort for Winter's first go at playing Chan. There are some oddities: Victor Sen Yung is now named Tommy instead of Jimmy, and he has been promoted from Number Three son to Number Two, and Charlie now lives in San Francisco instead of Honolulu. There's also a dated subplot with romance between the wisecracking girl reporter and the tough cop. That's understandable, though, considering this is a shot-by-shot remake of Monogram's 1939 Mr. Wong in Chinatown. Still, not too bad, especially considering this is a Monogram Picture directed by 'One Shot' Beaudine. Winters still reminds me more of Percy Dovetonsils than Charlie Chan, though...

Note: George Spaulding is listed in the opening credits, but nowhere to be seen in the actual film.
