A hypochondriac car thief, a hypnotic and ambiguous surgeon and a young, mean and incompetent telephone operator make up this noir story set between Italy and Switzerland, which enters the gray areas of the human soul. The operator falls in love with the voice of the car thief who "works" on a highway inhabited by a modern ghost, personified by the ambiguous and melancholy surgeon traveling in a luxurious black Bentley. Architects of their destinies and troubles, the hunters and the prey seek each other out, swap roles and find one another.
