A middle-aged woman servant arrives at a Victorian farm to assist a rheumatic old woman and her husband. She is, disguised, the 'evil' woman who tempted him to steal from his father and run away years before. She discovers the couple hate her, but father and son are reunited when the son is charged with her murder - part of her revenge plot. She attempts to burn his mother in her bed - and herself goes up in flames. (PB)
