New Zealand hunter Josh James and British chef Matt Tebbutt travel to Copper Canyon in Northern Mexico. Five times bigger than the Grand Canyon, it's one of the most spectacular natural landscapes in the world, but also one of the harshest. They will be dropped into the remote wilderness and will test themselves against nature, taking only the bare minimum of a kit. Josh has a bow and arrow, a slingshot, machete and fish hooks, while Matt has just a cooking pot, knife and water bottle. Using these basic tools they hunt and forage for everything they need to survive for seven long days and nights. Their aim is not just to survive, but to eat the very best food they can. Matt finds an unfamiliar Mexican agave and does his best to turn it into a mouth-watering meal. Josh goes hunting for the Canyon's famous wild turkeys and even manages to snare a raccoon, but disaster strikes when Matt begins cooking.

Repeated hunting failures leave the men exhausted, but hunger forces them to adapt to the harsh terrain and start thinking like the locals.

Matt's early success in producing a gourmet freshwater crab soup is soon forgotten as the forest turns out to be a hard place to find food.

If it works, they will have the wild feast that they have been waiting for.

With deep snow, treacherous ice, brutal temperatures and no obvious food sources, this punishing place is about to push these two men beyond the limit of anything they have ever experienced.
