Backpacker in Neuguinea

You are on a backpacking adventure through the remote wilderness of Papua New Guinea. Trekking deep into the jungle as dusk sets in, you emerge into a small clearing dotted with traditional thatched huts. Relieved, you approach the settlement to ask for shelter for the night. A member of the indigenous Korowai tribe ushers you inside a small hut. But before you can even settle in, he mutters a series of incomprehensible words, slips outside, and locks the door shut behind you! Trapped in the dark, you quickly realize you aren't welcome guests—you're prisoners.
