Prominent attorney Brad Mason takes on the defense of Rudi Walchek, a young hit-man hoodlum accused of murder. Convinced of the youthful thug's innocence, Mason get him acquitted. Later, he learns from the murder-victi...展开m's father that Walchek is a low-level member of a protection-racket gang and was undoubtedly guilty. Mason is anxious to get the gang-leader, but when he discovers it is the eminently respected head of the city's Crime Commission, he feels that a conviction in a court-of-law would be impossible. In a rage, he kills the man, but all evidence, including the murder weapon points to Walchek. When the latter is again brought to trial, Mason, although he senses a higher justice is at work, feels he must defend him with the best of his ability.
