Cari is devastated when her husband Martin leaves her for another woman.
Her friend, wide-boy Nigel, persuades her to get a bank loan and buy a house to do up for rental, but it soon becomes apparent that he's contravened every rule and regulation in the book.
She's lumbered with an infuriating mother, a friend who's permanently pregnant, and a friend who may be pregnant - but not by her husband - and her neurotic sister Juliette is on the verge of a nervous breakdown.
Her first tenant, Gary, turns out to be a drug addict on benefit. He moves in a dozen mates and barricades Cari in the flat while the police are battering the door down, ensuring that she's arrested along with the squatters.
And then her estranged husband announces that he wants to sell the house she's living in.
Could life get any worse?
At least her love life begins to get interesting. Pursued by spinsterish Henry, she has a fling with TV interviewer Guy, and then there's closet opera fan Ben the Builder, reassuring and more than presentable.
Cari writes a wish list: (a) Make some money (b) Lose some weight (c) Find someone to have a grand passion with and (d) Become so rich and successful that Martin is consumed with jealousy.
And suddenly, all her wishes begin to be answered...
