Roger Viceroy faces a return to the FBI and a life he vacated long ago, until a knock on his front door announces the presence of billionaire and former U.S. Senator, Jürgen Sandt. The past has come back to rear its ugly head. Sandt stands on his threshold for a reason: a decade prior the senator’s only son disappeared into the jungles of Guatemala, and Sandt has come to convince Viceroy that further investigation is now necessary. A package left mysteriously outside the family estate, opens the door to the possibility that his son is still very much alive. Viceroy and his team agree to take on the hunt.
