Moore finds out that Sonia, whose real name is Olivia Montello, is a deep cover CIA agent, while Corrales barely escapes.

Moore, along with a DEA agent embedded in the cartel as a sicario and his immediate boss, follow the couple and the Guatemalans to the nearby town of San Juan Chamula and rescue them.

Meanwhile, Taliban terrorists led by Mullah Abdul Samad approach the Juárez Cartel and try to enlist their help in smuggling them across the Mexico–United States border in order to carry out attacks in the north.

When Rojas refuses his offer due to the expected loss in drug profits, Samad and his team decide to go through the border themselves through a smuggling tunnel owned by the Juárez Cartel between Mexicali, Baja California, and Calexico, California, murdering the tunnel engineer and a drug mule (who is an asset of one of Moore's partners in the joint task force) in the process.

With the U.S. government out for blood, Moore later finds out Samad's whereabouts from his asset back in Pakistan, which is in a safehouse owned by the Sinaloa Cartel in Belize.

Along with task force leader Henry Towers and a contingent of British Royal Marines training nearby, Moore captures him.

Two weeks later, as he is waiting for a date with Olivia, Moore is approached by The Campus operative Dominic Caruso, who attempts to recruit him into the organization but later postpones his offer.
