Martha's posting to Agok, in South Sudan, gives her the chance to make amends for the mistake that caused her to be sent home from her last posting. As Project Manager, she's in charge of a small team facing an escalating crisis, with more and more refugees arriving across the border from the North, and violence never far under the surface.

As Martha's team try to deal with an ever-increasing number of refugees, she has a crisis of her own to deal with inside the compound.
