It's a comedy drama about 4 young people travelling around Asia, and the older guy they can't shake off (played by Tim Key, right).
It's set in China, Vietnam, Thailand, Malaysia and Nepal, so as much as anything else, it's a good way to see a lot of lovely places and briefly escape the poor weather/dire political situation.
