Lorraine Petrovich (Ann-Margret) is an eccentric woman who implicates her brutal & controlling lover in the murder of a young retarded girl.
Absorbed with "Murder She Wrote" and "Matlock", she creates details of the murder from clues she picks up from the detectives Jen Powell (Marg Helgenberger) and Dylan McCarthy (Henry Thomas) on the case.
Implicating herself and sentenced to jail, she then recants her testimony. But no one believes her until clues surface from the real killer that he is still out there, has killed before, and will kill again.
