After meeting with Amber, Hei learns that against common knowledge Contractors can become more humane than was thought to be possible. Realising his own position between the world of contractors and humans, Hei has to make the decisive choice for both. With final farewells to his past comrades inside the Gate, and their support behind his back, Hei's decision brings new future for the world.

Hei and Suo attempt to flee Russia, but their escape efforts are hindered by Contractors and gun-toting soldiers. As the body count rises, Suo finds herself undergoing a shocking metamorphosis.

Suo encounters someone she thought was dead and learns the truth behind the mysteries of her past. Unfortunately, the meeting is cut short when several Contractors launch an attack.
