When rhino poachers kill two of his fellow rangers in Kruger Park, South African Defense Force veteran Cobus Venter reaches his breaking point. Quitting his job, he embarks on a vigilante mission to take down the animal-trafficking syndicate from the inside. Meanwhile, in Florida, insurance investigator Randall Knight is called to a private roadside zoo, where a new tiger cub of suspect lineage brought a virus that wiped out all the zoo's tigers. The disease is just one species jump away from erupting into a deadly global human pandemic. What starts as a simple insurance claim leads Knight to discover a shocking new evolution in the business of illicit animal trafficking. Both men's journeys take them from the darkest corners of Southeast Asia to the VIP gambling rooms of Macau, where they must stay alive long enough to stop a vicious international triad from ending wildlife as we know it.
