For the last decade a war has been waged across the national parks and game reserves of Africa. A bloody conflict that that has resulted in the slaughter of thousands of majestic black rhinos. Driven by Asian demand poachers have pushed the species to the brink of extinction... and they have no intention of stopping. Ill-equipped, poorly-resourced park rangers are all that stand between these noble animals and total annihilation. With the PRIMAL team on hiatus Bishop and Saneh take a much needed rest at a national park in Zambia. But, before long their paths cross with ruthless poachers and tragedy strikes. Consumed by rage Bishop sets out on a renegade mission that tests his limits and ultimately his very will to fight.
