It's been ten months since Kate gave birth to the twins, her and husband Mick's sixth and seventh children, but he is still banned from the marital bed.

A devout Catholic and good friend of the local priest, Mick follows the church's teachings - literally - religiously, including the Papal ban on using any method of contraception. But the house is already fit to burst; they are forced to employ a live-in au pair to help take care of the brood; and Kate wants nothing less than to be pregnant. Again.

Accordingly, she has been barricading herself in the master bedroom every night, relegating Mick to a spare bedroom unless he consents to using protection - which he steadfastly refuses to do. And both sides in this battle of wills want nothing more than to be back in the other's arms.

When he begins, as if a mirage in a sun-parched desert, imagining that any attractive woman he sees - be it in the office, on the commute, or out in town - is completely naked, Mick realises that the problem is starting to have a far more deep effect on his psyche, and his every day life. That he works for a clothing manufacturer specialising in ladies' underwear and lingerie only brings the frustrations into yet sharper focus!

As tensions come to the boil, Kate offers a final ultimatum, Mick seeks Father Andrew's personal advice, and there are surprising goings-on concerning au pair Jackie, too.
