The Human Factor is slow-moving, cynical and emotionless. Also difficult to smallow is the presence of several fine actors. George Kennedy looks suitably frantic throughout, but is unable to make his predicament convin...展开cing due to poor scripting. John Mills has a major supporting role but his performance is as cold and inexpressive as the tone of the whole film. Raf Vallone (an Italian Oliver Reed look-a-like) meanders in and out of the story pointlessly as a policeman out to solve a multiple murder. The story has Kennedy as a NATO war-game computer programmer who lives and works in Naples, Italy. He returns home one day to find his wife and children dead, clinically executed by a mystery gunman or gunmen. He uses his computer access to track down the killers, and figures out that those responsible are a terrorist gang intent on murdering American families that live in Europe. Instead of passing this information on to the police, he decides to turn vigilante, tracking down and killing the terrorists himself.
