State Zero(2015)

State Zero is a Swedish sci-fi thriller set in a post-apocalyptic Stockholm. Four soldiers venture into the ravaged Zone 3 on a routine mission to investigate why an old surveillance tower has gone dark. What begins as a straightforward assignment quickly spirals into something far more dangerous and mysterious. As the team navigates the desolate landscape and abandoned structures, they uncover unsettling truths about the tower's shutdown and the forces controlling their world. Tension mounts as survival instincts clash with military orders, forcing the soldiers to question everything they've been told about their mission and their government. State Zero delivers a taut, atmospheric exploration of power, isolation, and the cost of obedience in a world stripped bare.
