John Cox is dead, killed in an explosion while at work. His younger sister Hayley can’t believe he’s gone. Determined to see the place of his death, she flies to Moscow with John’s fiancee, Annie-but the site they’re shown isn’t where John died. Suddenly it seems that there’s more to his death than a tragic accident. Using a tracking system to locate John’s mobile phone, Hayley and Annie find the real site of the explosion … but they are completely at the mercy of John’s former Russian boss and his English speaking son, who have taken them there. Upon recovering the phone, it’s clear that John is still alive. Meanwhile, in the Siberian forest, John is being nursed back from the brink of death by a village woman. As he slowly recovers he begins to piece together the truth: he’s at the heart of a dangerous power struggle between two brothers who are desperate to silence him-for good.
