An investigative reporter who spent his daughter’s childhood working flies to India to spend her birthday with her. She is gone before he arrives. What begins as a father’s search becomes a route march across a country he does not understand — Goa to Karnataka, Delhi to the foothills — chasing a network that is bigger at every turn than he was told. The trail ends at the edge of the Himalayas, at a valley that has been an unholy shrine to young European women for over half a century, and has never once been asked to explain itself.
