Set during the summer of 1957. Ex-racecar driver, Enzo Ferrari, is in crisis. Bankruptcy stalks the company he and his wife, Laura, built from nothing ten years earlier. Their tempestuous marriage struggles with the mourning for one son and the acknowledgement of another.
A divorced mother honks impatiently at a deranged middle-aged stranger at a red light while running late on her way to work. His road rage escalates to horrifyingly psychotic proportions as he becomes single-mindedly determined to teach her a deadly lesson for provoking him.
