A young married couple awake to find that the woman's jest about changing places with her husband has actually taken place. They have exchanged bodies. For the priapic Barrie it provides an ideal opportunity to explore Natasha's sexuality. Whereas Natasha is confronted with the challenge of controlling his rampant libido; something she had stated many time as simply a case of mind over matter. Natasha runs a blossoming lingerie business with a friend, so on his first day in her body, Barrie finds himself modelling a range of smoulderingly sexy lingerie to the lesbian buyer of a national chain of High Street stores. Using Natasha's beautiful body in a way which her partner, Debbie, has never witnessed before, he has the buyer begging for more, not realising that the object of her desire is really a hairy rugby player! Meanwhile, Natasha is having to deal with the company politics of Barrie's workplace, which includes giving sexual satisfaction to the CEO's personal assistant, in return for valuable information. Natasha quickly finds herself complicit in all his philandering and the prime murder suspect of one of his many conquests.
