Yvie first meets Adam and Pammy Clifton as neighbours in quarters in Germany, where she has been posted with her soldier husband, Richard. Their friendship is cemented by the shared experience of army life, but is put to the test when the relationship between Adam and Yvie turns into a short-lived but passionate affair.

Seeking refuge at the Clifton's home in the Lake District, together with her teenage daughter Claire, Yvie is all too aware of the smouldering attraction between herself and Adam, and is determined that it will not be reignited . . .
