A European import company is trying to put Chinese businesses out of action in Chinatown. The company is led by the Dragon Lady (Luana Walters) who hires Poten (Lugosi) to aid her. Poten is a mad racist who runs a string of crazy plans against the Chinese, foiled over and over again by keen reporter Joan (Joan Barclay) and her sweetheart Martin (Bruce Bennett)... oh and the police too. Things come to a head when Poten disguises himself as a Chinese waiter and plants to poison everyone at a banquet...
To be honest the final act is rather lame after a series of death defying cliff hangers which doesn't really make the struggle to get there that worthwhile. The serial isn't the most thrilling example in the genre, don't expect any death rays or other mad science. Do expect some rather awkward dialogue, sloppy execution (even by the usual standard of serials) and dated stereotypes.
