Al Walker is a violent prison escapee who kills a warden and takes a family hostage at a remote vacation cabin. He is portrayed as impulsive and volatile, driven more by anger than careful planning. He is haunted by recurring nightmares that hint at childhood trauma, and he becomes drawn to psychoanalytic ideas as a potential path to understanding his own violence.

Dr. Andrew Collins is a police psychiatrist and professor who uses dream analysis to understand Walker's psychology. He remains calm and analytical, attempting to translate clinical insight into a potential cure for criminal behavior. He embodies the era's faith in psychology as a tool for crime prevention while facing ethical questions about influencing a suspect's mind.

Walker's nightmares reveal a childhood trauma, witnessing his father's murder with his hand stained by his father's blood. The film explores how this buried memory shapes his violent behavior, even though Walker shows limited intellectual capacity. The story questions whether recovering this memory can actually cure crime or merely illuminate its roots.

The film presents Collins's therapy as a potential cure that could steer Walker away from killing, reflecting contemporary faith in science as a crime-fighting tool. However, the movie also raises ethical questions about manipulating a suspect's mind and whether therapeutic goals are truly transparent. The resolution remains ambiguous about whether memory recovery alone can actually cure criminal behavior.

The narrative centers on whether rehabilitation is possible for a violent offender like Walker. Collins's confidence in a therapeutic cure pits mercy against fear of relapse. The resolution suggests a protective outcome for society as much as potential redemption for Walker, prompting reflection on the limits of therapy in criminal justice.
