A hardened criminal, whose personality belies his viciousness, escapes from prison, killing a guard. Dan Mathews swings into action, and as the man commits one ruthless act after another to break through the trap closing in on him, it becomes apparent that there's almost a personal conflict between the two men - that ends only when they meet face to face in the final scene.

An expensive, giant computer, one of the twentieth century wonders, which does a tremendous amount of administrative work in just hours, is ingeniously 'kidnapped' from an electronics company by two men. The firm's owner is told to get $100,000 from his bank at two o'clock the next day and wait for instructions. A helicopter chase helps Dan stop the men from collecting the ransom or getting away.

Systematic traffic checks and increased patrols begin on a high accident freeway. Hoping to determine causes and cures, Dan questions drivers who get too many citations there. One man refuses to accept Dan's safety philosophy. When his license is suspended, his wife drives him to an important business meeting. En route, her eyeglasses break and he takes over at the wheel. Encountering a traffic check, he panics and flees, resulting in a severe accident in which his wife is critically injured. He learns the hard way - and too late - what Dan had earlier tried to impress upon him.

An uninvolved man happens to be in the company of two brothers who hold up a diner and kill its owner. Fearing the police and terrified of the vengeance he may expect from the criminals, he flees. As Dan searches for him, one man winds up dead, two critically wounded, and the man who a few short hours ago was an average law-abiding citizen is harried to the point where he is willing to shoot it cut with the police - until Dan manages to show the error of his ways.

Dan Mathews and his officers assist a county sheriff in closing down a club that offers illicit gambling.
