Dr. Paul Allen has a great, well-paid job, a loving wife, and two daughters. But his stable, planned life falls apart when, during an election campaign, the presidential candidate is killed—and the killer turns out to be Daniel, Allen’s son from his first marriage. Paul can’t believe his son is guilty, but the moment of the attempt was recorded on camera, and the Secret Service has no doubts: Daniel is sentenced to death. Trying to save his son, Paul begins his own investigation. The deeper he gets into Daniel’s life—the smart teenager who, at nineteen, unexpectedly quit school and wandered around the country—the more he is pulled into a dark world of secrets, homeless people, and eternal wanderers, government special services, and conspiracies. He begins to suspect that his son has become a pawn in someone else’s game, that he’s being set up, and that someone is trying to hide the true culprits of the murder. But the search makes Paul look at his own life in a new way: the past opens up before him in a different light, and harmless missteps turn into ominous signs. Paul always believed he was a good father—but what if he himself is also to blame for what happened?
