In a fit of rage, James stabs his own mother to death, before stabbing and wounding his father. Shortly before Nancys funeral, Donald passionately supports his son, provoking hostility from the rest of the family. At the funeral itself, James believes he has seen his mother and rushes over to hug her. In James eyes, she then stabs her son several times, though everyone else sees James taking the knife he killed his mother with into his own stomach.The film ends with Donald apparently bearing the same condition as his son, being cared for in his own home. He stabs one of the nurses, and is taken away. ........
