Nima uploads the virus at the last second, and the drone swarm over Isfahan shuts down in mid-air, raining harmless metal onto the empty desert. The summit proceeds.
Instead of a long gunfight, the climax is intimate and brutal: Behrouz vs. the son in a rain-soaked garden, knives and sheer fury. Behrouz wins but spares him—"Not for you. For our mother."
They discover the truth: The drones are being hijacked by a rogue faction within a neighboring country’s intelligence agency, using a black-market AI chip developed from Iranian university research stolen by a corrupt general’s son. The goal is to blame Iran for the assassination, triggering a U.S. retaliatory strike and collapsing the peace process. The brothers split up: Nima goes to the cyber center to upload a counter-virus; Behrouz goes to the general’s villa to physically extract the master control tablet.
Nima tracks Behrouz down in a chop shop where he’s installing a nitrous system into a yellow 1980s Peykan (Iran’s iconic national car). Their reunion is tense: “You disappeared for five years. Now you come because a machine wants to kill people? Machines don’t kill people, Nima. Orders do.” Nima: “The same orders you ran from. Now give me the decryption key, or I’ll take you in.” Behrouz: “You can try, brother .” A fight erupts—fists, wrenches, and a near-collision with a moving truck. But before Nima can cuff Behrouz, a silent drone swoops in and fires a railgun round through the shop. Someone else wants Behrouz dead. They escape in the Peykan, tires screaming.
