Explosions and fires kill and wound hundreds of people at simultaneous Fourth of July celebrations in Virginia and in Copenhagen, Denmark.

An unknown Islamist organization claims responsibility in Copenhagen, while the US government blames suicide bombers with ties to al-Qaeda for the American attack, deeming the two events to be unconnected.

Adam Stepowski, an investigative lawyer who witnesses the horror in Virginia, while his younger son escapes unharmed from the Danish attack, doesn't believe in coincidences. With his family, a Russian girl, and a retired CIA operative, Adam launches an independent investigation on both sides of the Atlantic. The facts he discovers contradict the official version proclaimed by the White House. Adam uses his international experience to find the link between Virginia and Denmark. As the mystery unfolds, Adam races to find an answer that will be more complex and alarming than he had imagined.
