Part 2: Jonathan Ross
Bear Grylls helps Jonathan Ross to discover his inner Tarzan on a once-in-a-lifetime expedition to the magnificent rainforests on the volcanic island of La Palma, one of the least-known of the Canaries. Bear challenges novice Jonathan with a series of exhilarating adventures during an intense two-day trip, including trekking through dense jungle with machetes, SAS-style fast-roping from a helicopter, a walk down an active volcano and sleeping in a cave in a steep cliff face. Bear and Jonathan have to fend for themselves, including preparing wild animals for food.

Part 2 reveals how Britain and America discovered compelling evidence that Pakistan was secretly helping the Taliban and concluded they had been double-crossed. It tells the story of how under President Obama the US has waged a secret war against Pakistan. Taliban commanders tell the film makers that to this day Pakistan shelters and arms them, and helps them kill Western troops - indeed one recently captured suicide bomber alleges he was trained by Pakistani intelligence. Chillingly, the film also reveals that, based on some evidence, Pakistani intelligence stands accused of sabotaging possible peace talks. Pakistan denies these charges, but relations between Pakistan and America now verge on hostility.
