It's late 2014 and a young British woman stumbles through the streets of Eckhausen in Germany and collapses. Her name is Alice Webster (Abigail Hardingham) --and she was abducted from the same town 11 years ago.
Her return sends shock waves 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 (Tcheky Karyo).
In present day, Alice's parents Sam Webster (David Morrisey) and Gemma Webster (Keeley Hawes) are barely speaking, whilst Alice's brother, Matthew (Jake Davies), has become violent and withdrawn.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.
