Thirty-five years later, Dominic Walker, a teacher, is arrested for murder - but his story is too fantastic for the police to believe... Dominic and Laura are rebuilding their marriage after a crisis. Dominic has problems, but his marriage is everything. One day, when Laura disappears unexpectedly, Dominic is left to try and work it all out. Months later she returns home out of the blue, bringing paradise back to Dominic's life. But something's not right. Laura has changed. As events become ever more peculiar and Laura's behaviour more unsettling, the tension grows. Dominic begins to wonder just who his wife actually is. And all the while, danger is lurking. Death is coming. The question is, for whom? And how are the events of thirty-five years ago entwined with the present?
