A story of the Michigan State Police and the strong sense of loyalty and duty it instills in its men. It follows the career of a newly-inducted rookie, Ross Martin, who has joined the force at the urging of his sweetheart, Mary Adams. Martin soon distinguishes himself by his bravery in the apprehension of criminals. But when the leader of a gang of bank robbers falls into his hands and then escapes, because of carelessness on Martin's part, he is suspended from the force.
