Be in the service of the devil, while “working” for the forces of good. No intelligence officer has ever received such assignments. But Marty had to make a pact with both the devil and the angel. The service turned out to be difficult: the need to maneuver between two gentlemen, the temptation of beauties, and familiarity with the laws of the devilish world seriously confused the hero. But the real problem arises when Marty realizes that each of his masters is playing their own cunning game. And the question of which side to take in this game cannot be resolved immediately - the boundaries between good and evil in the other world are blurred just as in ours.
