´I think you might be my father . . .´

Zoe Barry walks into Professor David Connelly´s office and tentatively says these words.

The lives of his family - particularly his wife Caroline - are turned upside down by the arrival of this stranger.

A cuckoo in their nest

Zoe soon entangles herself in their world but her stories aren´t quite adding up and Caroline isn´t sure she can be trusted.

Is Zoe who she claims she is, or someone with a far darker agenda?

A daughter, a sister, a stranger . . .

By letting Zoe in, David and Caroline aren´t the only ones who are vulnerable.

They´re risking the lives of the most precious thing in the world - the lives of their children . . .

. . . a killer?
