Plot

Mr. Moto is brought in by British intelligence to assist in their investigation of a plot to drive a major oil company out of business. Moto meets his old friend, Russell McAllister an American oil company executive, at a London restaurant. McAllister tells Moto that his company's operations in Iran are threatened by a campaign of sabotage and the Shahrdar of Wadi (a stand-in for the Shah of Iran) is threatening to cancel his company's lease. McAllister also believes that his own life is in danger. As McAllister and Moto leave the restaurant, the former is gunned down in a drive-by shooting. The car's driver, the Englishman Coburn and the assassin, the German Helmut "Dargo" Engle set off in pursuit of Moto who was slightly wounded down the dark streets of London. Engle, a former SS officer revels in killing and mocks Coburn for his nervousness, saying "the Oriental" as he calls Moto will be easy prey. When Moto goes into an abandoned house, Coburn follows him while Engle waits outside. Moto defeats Coburn in hand-to-hand combat and forces him to reveal he is working for a man who he only knows as "Dargo". When Coburn attempts to escape, Engle sees him and guns him down for his cowardice. Engle then enters the building, but Moto is able to escape by jumping off the roof.
