As an Afghanistan war veteran with linguistic skills stemming from her childhood as a missionary kid in Africa, Robin Duncan signs on with a private security company as a translator, hoping to use her pay to assist a niece with medical needs. The mission is to help local officials in the Congo combat rebels who have been attacking the mining operations of an overseas company. On the way into the country, she encounters an old friend from the war, also an MK, but whom she had lost touch with due to a misunderstanding. Michael is now a doctor with the group Doctors Without Borders, working at a newly re-established clinic in the same area as the mine.
