As war looms in Ukraine, Polish officials fight to safeguard the Suwałki Gap, a critical NATO territory sandwiched between Russia and Belarus. Hoping to leave her life in the Polish Secret Service behind after a devastating personal blow, agent Ewa Oginiec (Lena Góra) is sent on an undercover mission as consul to the embassy in Minsk, where she must navigate a complex web of allegiances to complete her mission -- and find her partner Skiner, who disappeared after Russian agents uncovered his true identity. A thrilling tale of espionage on the global stage, The Eastern Gate (Przesmyk) explores the high-stakes battle between intelligence agencies in a world gripped by the complexities of modern warfare.
