In 1976, four friends - Dan, Fred, Tim and Thierry - are on a bus along the hippie trail from London to Kathmandu.
With the help of Dan\'s backpacking son, a tattooed lady and a Buddhist angel, the ageing hippies try to solve a 25-year old mystery that takes them amongst Himalayan peaks, and towards the inevitable showdown with their past..
Soon, a trail of kidnapping and murder leads them across the Roof of the World.
A quarter-century later, mysterious emails invite the other three to pick up their share of the money, and they decide to reunite in Kathmandu.
Thousands of kilometers, numerous acid trips, accidents, nightclubs and a pair of beautiful Siamese twins later, they finally reach the counter-culture capital of the world, Kathmandu, and Fred disappears with the drug money.
After a drug deal goes wrong, the boys barely escape with their lives.
But everything is not going according to plan.
