Robert Mitchum delivers a top-notch performance as Harry Graham, a lonely and tender lout of a father who, released from prison after having killed his wife many years ago, has to start anew but must deal with his embittered teenage son Jimmy (Jan-Michael Vincent). Jimmy, seeking vengeance upon his father, tracks him from the prison where he was incarcerated to the run-down seashore community where Harry is now eking out a living in a trailer park with his girlfriend Jenny (Brenda Vaccaro). When Jimmy at last confronts his father face to face, he finds he has to deal with many unresolved emotional barriers in their relationship.
