Porter and Masuku become the hunted as a bushman tracker leads the relentless Zimbabwean authorities after them, and Layla Thompson becomes increasingly aware of the tension that exists between Porter and Collinson.

Porter's life is in danger when he finds himself trapped in a rebels' base in Pakistan. When he manages to escape, he learns that Hugh Collinson, the man he blames for the fatal hostage extraction of 2003, has arrived in Afghanistan to meet him for a final showdown.
