The Green Flame is the precious jewel which motivates the plot of this hectic mellerdrammer. J. Warren Kerrigan is his usual stalwart self as a private detective, employed by the Jewelers Protective Association. The PI goes undercover to retrieve the titular gem, which has been stolen by thieves and is now being passed like a football from one crook to another. When he isn't tracking down the villains, our hero is dallying with the luscious Fritzi Brunette. The Green Flame packs a lot of energy and excitement into its 60-minute running time.
