Agent Zeta

Four Spanish ex-intelligence officers are killed on the same day at four points on the map, and the thread linking them runs back decades to a covert operation in Colombia code-named Ciénaga. The CNI sends Zeta, its best operative, to find and shield the sole survivor, paired with a Colombian counterpart, Alfa, who seems to know rather more about that old secret than he is saying. Espionage in the classic register: buried history, an uncertain partner, and a clock already running.

Spy-thriller regulars will recognise the pleasures on offer, from cross-border pursuit to a conspiracy peeled back in layers, plus the tension of relying on someone whose motives keep shifting underfoot. Over two hours and change there is room for set pieces and for the slower work of reassembling the past, so expect a rhythm that alternates rather than sprints. Fans of European espionage with long institutional memories and a distinctly Spanish accent should find this a propulsive night in.
