Chillers: S1 E10 - The Stuff Of Madness Chillers

Christopher and Penny Waggoner are a well-off married couple living outside of London who both suffer from what might be called childish obsessions. Christopher works as a solicitor often living in a fantasy world where he dreams of "Louise", a woman he hasn't seen for twenty years, but whom he still loves. Penny stays at home and spends most of her time tending to "the garden", a large walled-in backyard filled with flowers and stuffed animals.
