In this season finale, María and Peniley pose one last question: Was García Luna a mastermind triple agent, or is there a systemic issue fostering corruption in the DEA? To find out, we zoom into the DEA’s role in the drug war and talk to an ex-DEA special agent and whistleblower. We also take a moment to remember the victims of the failed “war on drugs” and highlight their mothers’ efforts toward accountability and healing. Finally, Maria and Peniley take one more trip where they give us a final revelation – this time to the place where García Luna spends his days awaiting his day in court.
