Four Spanish ex-intelligence officers are assassinated simultaneously worldwide. The CNI discovers all participated in the covert "Operation Ciénaga" decades ago in Colombia. Zeta, the CNI's best operative, must hunt and protect the sole survivor, facing his deadliest global mission yet. Top Colombian agent Alfa will join Zeta, seemingly knowing more about "Ciénaga"'s secrets than him.

Bogotá's neon rot versus Madrid's bureaucratic gray—two hells, beautifully shot.

Dani de la Torre
Trivia, insights & behind the scenes
Operation Ciénaga riffs on real Spanish intelligence collaboration with Colombian paramilitaries in the 90s—de la Torre practically dares audiences to Google it.
The hotel fight took six days to shoot; Casas performed his own stunts after a month of Krav Maga training, then immediately got food poisoning from on-set catering.
