The story follows two soldiers, Sergeant Allen Isaac (Aaron Taylor-Johnson) and Corporal Shane Matthews (John Cena), who are on a mission in Iraq to investigate a bombing. After an ambush by an enemy sniper, Isaac and Matthews find themselves pinned down by the sniper’s fire behind a crumbling wall, unable to move or communicate effectively with their comrades. Matthews is injured, and Isaac is left alone to try to survive and outsmart the unseen sniper, who is revealed to be a skilled and ruthless opponent.

The film is a tense and focused exploration of the psychological toll of warfare. The claustrophobic setting, with the characters trapped behind a wall in a desert landscape, emphasizes the theme of isolation, both physically and mentally. As Isaac tries to stay alive, he is forced to rely on his wits and the limited resources at his disposal to turn the situation around. The film moves from a straightforward survival tale to a deeper exploration of the psychological effects of warfare, as Isaac tries to piece together clues about the sniper’s idenтιтy and motivations.
