Being in love was her dream. Being her lover was his nightmare.

Janet Flanders is a small-town, unsophisticated young woman who is seduced by the fantasy of romantic love; she believes that someday her prince will come to sweep her away. Then she meets handsome Brett Becker; she believes she's found the man of her dreams -- little suspecting he is engaged to marry a wealthy socialite. Deep into her illusion that Brett loves her, she moves to Chicago to be closer to him, deluge him with calls and love notes, tells her family about her boyfriend Brett, and buys an engagement ring. Her obsession with him leads her from intrigue and eventually to murder.
