Pegg plays Hector, an eccentric yet irresistible London psychiatrist in crisis: his patients are just not getting any happier! He’s going nowhere. Then one day, armed with buckets of courage and an almost child-like curiosity, Hector breaks out of his sheltered vacuum of a life into a global quest to find out if happiness exists. More importantly, if it exists for Hector. And so begins a colorful, exotic, dangerous and hysterical journey.
