Epic journey series. Now in far-flung Vietnam, Charley joins thousands of local bikers on a Minsk motorcycle rally, and makes his way over to Halong Bay to see the beauty of the Thousand Islands and meet traditional pearl makers. However, it is not long before this peaceful excursion takes a turn for the worse - nerves are quickly on edge as the team, now aboard a very small speedboat on rough seas, are pounded by the water. A wave kills the small engine just as the boat swings in towards the rocks, but the team's loud screaming alerts a nearby fishing boat, and luckily they are pulled out of danger just in time. Charley gets back on track behind the wheel of a US military jeep to visit some of the most significant places from the Vietnam War, such as Vinh Moc and its infamous underground tunnel network, built by the villagers to escape the devastation. In Laos and Cambodia, Charley experiences the wonders of the Mekong River aboard a powerful rocket boat. Enjoying the largest waterfalls in South East Asia and then dirt-biking his way around the countryside, he finally marvels at the 11th-century ruins of Angkor Wat. Traveling south through Thailand and Malaysia, Charley tries out an unfamiliar form of transport to cross to Singapore - wakeboarding. Successfully across and now on Nikoi Island, Charley is to board a small cargo boat that looks well beyond its sell-by date. After some pre-departure prayers, it is not long before he and the crew are far out at sea and another boating misfortune strikes - the boat has sprung a leak, and is rapidly taking in water.
