SIN FANG ADVENTURE SERIES (1928)-The Adventure of the Torture Cage. Tinted

Only one episode of the SIN FANG ADVENTURE SERIES (1928) evidently survived: "The Adventure of the Torture Cage."
In this fifth chapter. Lt John Byrne and Bill Riggers are on the hunt for the criminal doctor Sin Fang, who is hell-bent on locating a lost ‘sacred seal’. A trader hoping to make a quick buck on the seal is lured to Fang’s lair, where he and Riggers are held prisoner in Fang’s torture cage. Only Byrne’s fiancée, Betty Harbray, can save the day.

Dr. Sin Fang serial borrowed many of the performers (including the lead villain and plot elements) from the hugely successful Fu-Manchu serials. Producer Fred Paul had played Nayland Smith in The Mystery of Dr. Fu-Manchu and went on to direct The Further Mysteries of Dr. Fu Manchu. Star Harry Agar Lyons brings much of Fu-Manchu to his portrayal of the lesser-known, but also a sinister genius, Sin Fang. This serial was made on a much lower budget than Fu-Manchu and only ran to six parts - this was the final one.
Like the earlier Fu Manchus, this series is really a serial, because the feature main character (Sin Fang) survives every effort to eradicate him. The very episodic nature of of the series makes it a serial.
