The film follows a man who signs up for Atropia, a hyper-realistic military training city meant to replicate Middle Eastern battlefields. What begins as controlled immersion fractures into paranoia as civilians behave unpredictably, soldiers lose control, and staged conflicts feel increasingly real. The trailer builds dread through malfunctioning systems, blurred identities, and a psychological descent that makes every street corner a threat. Vertical frames it as a tense, disorienting thriller where trauma refuses to obey the script.
