In Boston, Popsy Power is pretty, popular and insanely rich. Her husband adores her and her two daughters are busy producing babies and romping up the corporate ladder – like good little Wellesley Wives. HOWEVER, what Popsy doesn't know is that her husband and worldly wealth will soon be gone and as for daughters? Well, Lily's romping is not restricted to the boardroom and Rosie finds her pilot–husband flying more than his jet airline...

Sandra is Popsy's best friend. She has the perfect body, bank balance and palatial penthouse. As a second wife herself, she should know how husbands can wander but even she is shocked when she discovers where Jack has found his fun ... When Lily's nasty little secrets suddenly go public and Rosie finds her husband flying a little too high, it's time to escape.

Popsy and Sandra flee to beautiful, peaceful Ireland. Rosie heads to Mexico and Lily seeks refuge in the arms of her man. The adventure continues for Popsy and Sandra because within days they're almost arrested, killed and then they find themselves in a boathouse in Banagher – with jobs! Meanwhile Rosie is diving off the back of a catamaran into the azure–blue of the Caribbean but she's not sure which are worse – the sharks in the sea or the ones on the beach. The only one back in Boston; Lily discovers that getting what she wanted was not what she wanted but unlike her scuba diving sister, surely she's in too deep?

From Banagher to Boston and down to the Caribbean Sea these four ladies are on a rollercoaster ride through life. Rich, poor, happy, sad, in or out of love – only one thing is certain. Things are is never dull when you're with the Wellesley Wives.
