Koko doesn't want to change the world, she wants to own it, and the show never flinches from what that actually costs. Every gunfight is precise choreography in service of a woman whose smile gets colder the more she wins. You're watching someone brilliant and irredeemable build a private army one ammunition shipment at a time, and the show trusts you to find that compelling without ever asking you to forgive her.

Koko Hekmatyar is a young international arms dealer who sells weapons through HCLI, a shipping corporation, while pursuing an idealistic dream of world peace. Because most of her trade breaks international law, she must keep dodging local and international authorities as she deals with armies, private militaries and militias. Jonah is a child soldier who hates weapons and the people who sell them, yet he joins her as a bodyguard, hoping to find the dealer responsible for his family's death. Alongside her other guards, mostly former special-ops soldiers, he travels the world protecting Koko from assassins and a CIA that is always close behind.
