Lieutenant Davis and Captain Walsh send BRAVO to Thailand to partner with the DEA on a joint-task force focused on the fentanyl trade. The goal is to intercept a cargo ship and acquire intel that details the Chinese government's involvement. Drew is assigned to BRAVO full-time despite his objections and a journalist later questions him about his family's history. During the mission, Drew goes rogue and makes a decision that jeopardizes everything.

BRAVO targets a factory in Myanmar that the DEA has tied to China and fentanyl production. Lieutenant Davis wants the team to pull intel and destroy the plant. Jason vies for a safer plan, and some on the team begin to question his decisions.

BRAVO's back together and sent on a mission to verify concerning intel that links China's drug trafficking to a potential coup in Honduras. Before leaving, Jason, Ray and Drew all struggle with something personal, resulting in a volatile dynamic.

BRAVO finally finds some fentanyl, officially linking Nazario to the smuggling operation. Despite instructions to keep a low-profile, Jason destroys the fentanyl and kills all the guards. Later, the team makes a shocking discovery at Nazario's camp.

BRAVO returns from Nazario's camp stunned. Forced to regroup, the team hastily develops another plan to capture him, but they walk right into a trap. Later, Jason is pulled from the mission by Command and given a different objective.
