Long before REBECCA De MORNAY's hand rocked any cradle, serpentine usurper extraordinaire STEPHANIE ZIMBALIST rocked the worlds of extreme overacting power duo WILLIAM SHATNER and PATTY DUKE. As the icy 18-year-old Joanna Redwine, ZIMBALIST elbows her way into the squabbling couple's homestead insuring its downfall, if not by her manipulations than by the termite like power of the couple's own competitive scenery chewing. Of course Joanna is a gift from God at first, taking daughter QUINN CUMMINGS under her wing and throwing about helpful bon mots, but before long, she's making goo-goo eyes at SHATNER and pushing PATTY towards the bottle. It doesn't take much convincing to get mom to put on her VALLEY OF THE DOLLS lampshade and soon she is slurring her words more than the elocutionary impaired QUINN. Dad is a harder nut to crack, but when he walks in on Joanna wearing his wife's lingerie he too starts to melt to her will. (In this 1980 TV movie's most bizarre break from reality, ASTIN and ZIMBALIST wear the same size). Thanks to JOHN HOUSEMAN's detective work, which mostly consists of calling people on the phone, Joanna's reign is short lived. With the discovery of her previous employers packaged in clear plastic, she is carted off to jail. The dysfunctional Benedict family is free to return to their previous existence but whether that is an improvement is this tales biggest mystery.

INDELIBLE SCENE(S):

• ZIMBALIST wandering around her previous victims' home, and talking to the former occupants as if they were still alive
• Family perfectly preserved in plastic wrap on the master bed
