Paul Wood is a modern vagabond, a man who chooses to leave the comforts of San Francisco to spend months backpacking through some of the world's most challenging terrain: Cameroon, Indonesia, Nepal. While hiking in the Himalayas, Paul gets more of a rush than he bargained for when he finds the body of a murdered hiker, the victim mutilated in a way that Paul has witnessed once before, years ago and thousands of miles away.
