A young Parisian advertising executive becomes so captivated by the unsettling charm of his mysterious new employer that he eventually abandons his family and friends, viewing it a privilege to let the ubiquitous employer take over his home, his life, his desire. Only his wife remains suspicious, recognizing both the pathos and the evil in the man’s soul-stealing power.
