Enrico Melotti, a middle-aged businessman, has a difficult relationship with his wife, maid and secretary/lover. During a business trip to America, his friend Arturo shows him the key to solving all of his problems: Caterina, a female-looking robotic maid that does all domestic chores better than any human.

Faccia di spia tries to tell the story of the CIA and other government intelligence agencies with lots of re-creations and dramatizations and points out some of the more brutal aspects of the intelligence community from around the world. Wars are started, all facets of everyday life are controlled, innocent people are tortured needlessly and subjected to extreme violence.
