Revenge is in the air, as the head of the Gerstel cartel seeks to punish the man who killed his brother and everyone involved in his arrest and extradition to the United States. With John's real identity exposed, he must once again lock horns with Gonzalo Bravo to rescue his wife and sister-in-law, who were kidnapped to force him into the cartel's hands.

As the cartel's revenge plot grows, John is asked to protect the president from an assassin determined to take on the Secret Service and kill the United States President.
