Mr. Wong is a "harmless" Chinatown shopkeeper by day and relentless blood-thirsty pursuer of the Twelve Coins of Confucius by night. With possession of the coins, Mr. Wong will be supreme ruler of the Chinese province of Keelat, and his evil destiny will be fulfilled. A killing spree follows in dark and dangerous Chinatown as Wong gets control of 11 of the 12 coins. Reporter Jason Barton and his girl Peg are hot on his trail, but soon find themselves in serious trouble when they stumble onto Wong's headquarters.
Unfortunately the movie The Mysterious Mr. Wong is not yet available on Disney Plus.
