Arriving home from a short holiday in Dingle, Lily Crossways makes a staggering discovery - on one of her photos taken on 'Inch Beach', a woman's desperate face is staring directly at her. Yet Lily knows she was alone that day on the beach. Who is she, is she even real, and why has she appeared to Lily? Unable to let the woman go, Lily makes the uncharacteristic decision to leave behind her safe world in England and return to Dingle to try and find her. Her search eventually leads her to cafe owner David Carson, this woman's brother, who hasn't seen his 'missing' sister in five years. Lily must now convince him to trust in her, taking bold steps to prove herself to him, and together track down his sister before it's too late. Yet are either prepared for the hidden secrets they are about to uncover in their earnest desire to find her, and the impact it will have on those they love?
