An acclaimed doctor, Dan Marsden, is shot through the skull in the living room of his remote country home, and his two daughters, Karen and Mira, are taken against their will. Meanwhile, a new DC, Barry Kelman, is temporarily assigned to the team to help them with the investigation. Initial suspicion falls upon Jonah Regan, an award-winning photographer who had previously tried to adopt Mira before the Marsden family were granted custody. However, it soon becomes apparent that one of Mira's relatives - her estranged brother, Malik - who was thought to have died in a bomb attack in Baghdad - is in fact alive and well, and has been contacting her through her social media accounts. Malik, however, is determined to flee back to his homeland with Mira in tow - but when he comes face to face with Laura Marsden and DC Kelman, tragedy strikes.
