Agent Zeta

Four former Spanish intelligence agents are mysteriously murdered across the globe in a coordinated strike. The CNI uncovers that all four were involved in a clandestine operation called "Operation Ciénaga," conducted years earlier in Colombia. Zeta, the agency's top operative, is tasked with tracking down and safeguarding the only remaining survivor of the operation, confronting his most dangerous international mission to date. To complicate matters, renowned Colombian agent Alfa teams up with Zeta, appearing to possess deeper knowledge about the secrets of "Ciénaga" than anyone else.
