Man's best friend is a poacher's worst nightmare, but tracker dogs and their handlers protecting wildlife in Africa face an explosive new threat. Can a man and his dog find redemption and the real criminal?

Afghanistan veteran Sean Bourke's world explodes when an IED detonates in South Africa's Sabi Sand Game Reserve.

On a routine anti-poaching patrol, Sean and his tracker dog Benny watch in horror as over-eager rookie Tumi Mabasa is almost killed and her dog gravely injured in the explosion.

Along with Tumi and best mate Craig Hoddy, Sean is determined to hunt down the elusive bombmaker who has introduced this destructive weapon to the war on poaching.

But Sean is his own worst enemy. Haunted by nightmares of the war and racked with guilt from driving away his ex-wife, Christine, he soon discovers she and Craig are in the midst of an intense affair.

And there's another enemy at play...
