Increasing tiger attacks are putting a rural Indian community on the frontlines of a conflict between man and man eater. Dave Salmoni is on a mission to find out why fatal attacks are on the rise. Putting himself at risk, Salmoni uncovers one recent case that reveals a shocking development in the tigers' deadly strategy, helping explain why the crisis is worsening and what might be done to solve it.

Dave Salmoni understands what makes hippos so deadly, but on Zambia's Zambezi River, he's entering a world of African witchcraft and sorcery that makes him rethink everything he believes about animal attacks. As a zoologist, Dave struggles to explain Zambia's most vicious hippo attacks, until his scientific approach meets local beliefs. He enters a world of witches and witchdoctors, where evil sorcerers possess hippos and make them kill. Dave is skeptical until he witnesses a hippo exorcism ceremony that leaves him amazed and confused. After this journey, he never will look at animal attacks the same way again.

Zoologist and large predator expert Dave Salmoni isn't a stranger to danger, but this is his first time on the front line of a war between humans and elephants. Joining forces with an armed elephant squad, Dave helps defend the villages of North East India from rampaging elephants in the dead of night. In the past 10 years, hundreds of men, women and children in this region have been trampled to death by the planet's largest land mammal, and the situation has just reached a crisis point. It's one of the most hostile wildlife war zones on Earth, but what has happened to make these beasts become so dangerous?
