Leighton Mills is a man on the way up — until an incident with too many glasses of champagne, a randy junior British Royal, a limo's back seat and a paparazzi photographer. Now Leighton finds himself diplomatic attaché to the nondescript villa that is the Auckland embassy of The Most Royal Kingdom of Fe'ausi. Jonah, the ambassador, is a whale of a man with an XXL personality and a talent for scams. However, Jonah has an Achilles heel: his beautiful, headstrong daughter Leilani. Banned from The Most Royal Kingdom of Fe'ausi for her leadership of anti-monarchy stirrers, she has been sent to New Zealand. And when Leighton sees her, his heart goes badaboom…
Fo'alafa Day, the Feausian equivalent of April Fool's Day, gets off to a cracking start with consulate 'babysitter' Leighton hosed down after a hoax anthrax-in-the-mail scare perpetrated by Suga, officially the consulate's tourist affairs liaison (but unofficially a bit unhinged and a lot scary). Leighton's suffering is brought to an end only when the object of his adoration, Leilani, arrives and tells them to leave him alone. Leighton then has the duty of reporting that Cyclone Joseph, which was going to miss the Fe'ausi Islands, has turned south and is heading straight for Ma'akiaveli, the capital city. When Leighton reveals this to be a prank, Fo'alafa Day takes another turn. Jonah reveals that they all knew it was a prank — but that Cyclone Joseph has actually turned a bit south and is heading for Fa'a'fele, an outlying Fe'ausian island, home to a colony of lepers and the nuns who look after them. Now just who is pranking who here?
In an attempt to buy Leighton off with the baubles of power, the Fe'ausians want to make him the first ever non-Fe'ausian Aratika (high chief). Unfortunately for them, Leighton has been reading his MC Hamer (the German anthropologist and expert on Fe'ausian customs) so he is only too happy to accept their offer because he knows being an Aratika will give him direct access to the King on matters where the good name of Fe'ausi is being besmirched. Unfortunately for Leighton, Mick unearths an appendix to the MC Hamer which outlines the gruesome and humiliating rituals prospective Aratikas used to have to undergo. Jonah decides it is high time these rituals made a comeback.
For once it is Leighton who must try to save the Fe'ausians from their own greed, as they plan to sink all the money they have made from phosphate mining Kakapu Atoll into an extremely dodgy West End musical. Of course, most of the staff at the Auckland embassy of The Most Royal Kingdom of Fe'ausi get bitten by the theatrical bug and want roles in the musical, whose show-stopping numbers include, naturally, a big fat finale called Knocked The Bugger Off.
