When Joe Lynch sees his wife enter an underground car park in the middle of the day, he's intrigued enough to follow her down. And when he sees her in an angry altercation with family friend Ben, he naturally goes to her defence. It's pure misfortune that, just as the clash becomes violent and Ben is knocked unconscious, Joe's son has an asthma attack, and Joe has to take him to safety. But when Joe comes back to check Ben's OK, he's disappeared. And that's when Joe receives the first message... What if your whole life was based on lies?
