A young British woman stumbles through the streets of Eckhausen in Germany and collapses. Her name is Alice Webster, and she was abducted from the same town 11 years ago. Her return sends shockwaves through the tight-knit local community, as her family are thrown into turmoil.
As the search for the abductor gathers pace, Alice also appears to hold vital clues to the whereabouts of a second missing girl, Sophie Giroux, whose disappearance was investigated back in 2003 by French detective Julien Baptiste.
Two years on, Alice's parents Sam and Gemma are barely speaking, whilst Alice's brother Matthew has become violent and withdrawn. Meanwhile, Julien is in Iraq, following a clue that he believes is key to finding the person who abducted the girls.
