A starving young immigrant doctor of Italian and Greek descent, Dario Asfar struggles to establish his practice, and is desperate to provide for his wife and newborn son. When the vulgar, self-indulgent French aristocrat Philippe Wardes dismisses his personal physician's advice to abstain from alcohol and gambling, he turns to Dr. Asfar for a second opinion. Understanding the opportunity before him, Dario obliges Wardes, and others like him, knowing well that the rich want to eat of the forbidden fruit without paying for the sin. At first Dario's plan is just for survival, but soon he begins to enjoy increasing rewards by selling himself as a master of souls who can miraculously cure restless minds, and in so doing sheds light on the lies we tell ourselves in the name of family and love.
