The last time Bob visited Pakistan was to report on the war in neighboring Afghanistan. Twenty years later, he's back with his son Mack to see a different side of the country. Mack knew Pakistan only as a place his dad went to report after the 9/11 attacks. But the Pakistanis they meet are eager to showcase their country's beauty and culture. Beginning in Malala's hometown in Swat Valley, Bob and Mack follow an ancient Silk Road route to encounter treasures that Pakistan's years of struggle have overshadowed: ancient carvings of the Buddha that survived Taliban rule, staggering snow-capped mountains, healing traditions that date back millennia and along the way learn to play cricket and polo -- two of the most popular games in the region. After months on the road together, Mack and Bob begin to get on each other's nerves. They spend their first car trip in separate vehicles and have a chance to vent. The duo patch things up on a father-son hike in a valley named after the mythic and mysterious Shangri La where they realize what made their trip through Pakistan so special.
