****SPOILERS**** International crime fighter Mister Kentaro "Kenny" Moto, Peter Lorre,is on a mission to see that the Chung family heirloom scrolls-all seven of them- stays in the family and not stolen by a gang of thieves to guide them, by putting the scrolls together, to the tomb and treasures, worth up to 10 million in gold and jewelry, of Mongolian chieftain Genghis Khan. It was first that Moto had to deal with Colonel Tchernov,Sig Ruman, who attempted to get Prince Chung,Philip Ahn, to hand the scrolls over to him, by pulling a gun on the Prince, by offing him with a fatal judo chop-off camera-and making it look like he killed himself.
It's then that the late Colonel's wife Madame Tchernov, Nedda Harrigan, had her goons try to get Moto to tell them where the scrolls were or else they'll not only kill him but Prince Chung and his mother Madame Chung, Pauline Frederick, as well. The attempts to murder Mr. Moto by Madame Tchernov's goons fell apart with him outwitting them at every occasion. But it was prince Chung who gave into them when they threatened to murder his mother who in fact was more then willing to die and in fact did then to give up where the scrolls were hidden.
***SPOILERS*** It was when Mister Moto turned Madame Tchernov against her lover the real boss of this criminal operation Herr Koerger, Sidney Blackman, by claiming he was going to drop her for pretty socialite Eleanor Joyce ,Jayne Regan, which caused the two now ex-lovers to turn on each other. That give Moto the chance to gun down Koerger and neutralize, by having her arrested, Madame Tchernov when all the dust cleared. In the end Prince Chung committed suicide for dishonoring his ancestors by revealing where the scrolls were hidden but Mister Moto cleared all that up by burning them in preventing any more people getting killed over them as a favor , that he made while he was still alive, to the late Prince Chung!
