Agent Zeta

When four former Spanish intelligence officers are assassinated in different parts of the world, the CNI begins investigating their shared past. The agency discovers that all four were once involved in a secret operation known as “Ciénaga,” carried out in Colombia years earlier. CNI agent Zeta is assigned to locate and protect the only surviving member of the operation, but what begins as a rescue mission soon becomes his most dangerous assignment yet. He is joined by Colombian agent Alfa, who appears to know far more about the hidden secrets of Ciénaga than Zeta ever expected.
