Death is their business, and business is good.

Jonah is a child soldier, born amidst the chaotic conflicts that rage across West Asia, his family lost to a war fueled by weapons supplied by the so-called Merchants of Death--international arms dealers. Despite Jonah's hatred of weapons and violence, he employs both extremely well in the service of high-flying arms dealer Koko Hekmatyar and her band of mercenaries. Their journey through the dark underbelly of the world's arms markets may lead only to damnation, but will Jonah one day make his way back to the light? Only one thing is certain: it's going to be a long, hard road out of hell...

Koko Hekmatyar's brother Kasper and Jonah face each other down, but settling old scores may have to wait a bit longer. Then Koko and her team head for South Africa looking for Japanese robotics scientist Dr. Minami Amada, whose inventions have profitable military applications. Naturally, the competition would like to meet the good doctor as well, and the race is on to find her. In the international arms trading game, Koko likes to keep her friends close and her enemies closer, but getting too close to Koko is a good way to end up in a body bag...
