In "Agent Zeta," a gripping international thriller, four former Spanish intelligence officers are mysteriously assassinated at the same moment across different parts of the world. These men all share a dark past, having been involved decades ago in a clandestine operation in Colombia known as "Operation Ciénaga." The simultaneous attacks send shockwaves through the Spanish National Intelligence Agency (CNI), forcing them to uncover the truth behind these coordinated murders.
The CNI's top field agent, known only as Zeta, is thrust into a relentless and perilous mission unlike any he has encountered before. Charged with hunting down the elusive perpetrators and safeguarding the only living survivor from "Operation Ciénaga," Zeta must navigate a deadly global web of espionage, betrayal, and hidden agendas. His quest for justice challenges him to confront shadows from the past while facing enemies who are always one step ahead.
Adding complexity to his mission is the arrival of Alfa, Colombia's premier intelligence operative. Alfa's involvement piques Zeta's suspicion, as she appears to possess intimate knowledge about the secrets surrounding "Operation Ciénaga" — perhaps even more than Zeta himself. As their uneasy alliance forms, the two agents must reconcile their conflicting motivations to uncover the truth behind the operation and bring those responsible for the assassinations to justice. Together, they dive deeper into a world where trust is scarce, and danger lurks at every corner.
