On a remote island off the coast of Tasmania, an Australian wilderness guide embarks on a four-day hike with six guests—and arrives at their destination with only two.

Devils Island is home to abundant wildlife and is the ideal place to re-introduce endangered Tasmanian devils. It’s also a region where travelers can see firsthand the unspoiled drama of Australia’s wild places. For naturalist guide Kerry, the trip offers a respite from the grueling work of trying to save an endangered species. American college classmates Brooke and Jane have a chance to reconnect after years of estrangement. Two Australian couples hope to escape their big-city lives and enjoy the company of longtime friends.

When Jane disappears on the first night, the group assumes she has wandered too far in the stormy weather. Yet it turns out she has a secret connection to one of the other guests—and when another hiker is found dead in camp, the group finds itself isolated by the worsening storm and wondering who among them might be responsible.
