Tough district attorney Jim Stowell (William) believes every murderer deserves to be sentenced to death, regardless of circumstances. He prosecutes elderly Professor Shaw MacAllen (Morgan) in the murder of his wife, who was killed in a fit of jealous rage, and wins the death penalty. However, Jim discovers fierce jealousy himself when family friend Phil (Lunigan) pays too much attention to his neglected wife Lucy (Patrick). In the coming days, Shaw's rage and jealousy grows over Lucy and Phil's innocent friendship, leading to thoughts of killing his wife and friend. Jim almost murders Lucy, but stops at the last moment, coming to understand Professor MacAllen's motivation for murder, having experienced it himself. He then tries to stop the execution.
