After a young man goes missing on a stag do in the Wyoming wilderness, an unlikely group of volunteers get together five years later to try to find him. The group – including the missing man’s father, and a Big Foot hunter – must hike deep into the woods in search of answers.

Richard and Judy are joined by author Lisa Gardner, whose research for the book included a wilderness survival course. She shares what she learnt, including how to make a fire, whether to prioritise food or shelter, and how to use the flora as medicine.
