Zee and Co.

Approaching middle age, the Blakeleys, architect Robert (Sir Michael Caine) and his brash, overbearing wife Zee (Dame Elizabeth Taylor), are Londoners who are able to indulge in their collective and individual narcissistic wants because of their financial standing and the fact that they have no children. They have a passionate love and hate relationship based largely on those individual wants. At a party, they meet widowed Stella (Susannah York), a couturier. Robert is immediately attracted to her. Robert and Stella openly embark on an affair, which for Robert is merely the latest dalliance in his life. However, the two fall in love, as, for Robert, Stella fulfills those parts of his life that Zee can't or won't since Stella is the antithesis of Zee: understanding with an air of serenity. Zee does whatever she can to disrupt what seems to be the idyllic life that Robert and Stella have set up for themselves, moving from one measure to another as each successive one doesn't achieve what Zee wants. Through it all, Robert and Zee continue on with their love/hate relationship, one where Stella may merely become a pawn for them to play with, especially as Zee discovers something from Stella's past.
