When she stumbles across the advert she's looking for something else completely. But it seems like too good an opportunity to miss: a live-in nanny position with a staggeringly generous salary. And when Rowan arrives at Heatherbrae House she is smitten by the luxurious 'smart' home fitted out with all modern conveniences by the beautiful Scottish Highlands and by this picture-perfect family. What she doesn't know is that she's stepping into a nightmare - one that will end with a child dead and her in a cell awaiting trial for murder. She knows she's made mistakes. But she maintains she's not guilty - at least not of murder. Which means someone else is.
