Wrestling with a mid-life crisis, Plum, a long serving public servant, identifies a scam to siphon off millions of pounds of cash from the City Council. Good detective work and a healthy sense of fair play finds him drawn into fighting the plot led by a corrupt politician, his greedy Chief Executive and some nasty henchmen and hangers-on.Reluctant at first but increasingly warming to the task, Plum falls back on his experience. His cunning and emerging resolve leads him to wage an idiosyncratic and effective guerilla campaign against the those who would profit from the corrupt award of a suspect contract. Ruthless big business and shady moneymen looking for an under the counter kick back lurk in the background.Something has snapped in Plum. He has had enough and he wants to get even. Assisted by an eclectic group of colleagues he sets out to frustrate leading politicians, his Chief Executive and the sycophantic group surrounding them.

Sticking to the shadows, Plum uses every lever and device and a wealth of experience to create chaos and confusion with increasingly hilarious results.The front line is the corrupt re-negotiation of a major contract with Servotex, a major outsourcing contractor. Here, Plum throws a full set of spanners in the works.Plum divides his time between orchestrating an elaborate set piece final reckoning with full media coverage and masterminding a series of colourful and increasingly hysterical skirmishes designed to divert attention, weaken and embarrass his adversary.Plum's guerrilla resistance campaign drags his adversaries into firefighting a series of side-actions and forces the opposition to dissipate energy chasing down a range of diversionary flare-ups.His resistance partners, some unwitting, include trusted colleagues, a cross-dressing chef, a colourful politician with a private army of sociopaths, a cynical journalist, a Hell's Angels chapter and attendees at a neo-fascist conference.They are up against a corporate machine, a wily, hard-nosed politician with his eye on a knighthood, a bullying scheming chief executive looking for a lucrative retirement job funded by the taxpayer, a slimy lawyer conducting a vendetta against moles and a former apartheid enforcer who seizes an opportunity to practice old skills.As decision day to award the contract approaches, so Plum's increasingly anarchic efforts increase in intensity and as pressure builds, so cracks in the city council establishment develop.

On the final day, the outdoor press conference to broadcast the Servotex decision is thrown into chaos, with police, army cadets, fascist thugs, a prison riot hit squad, RSPCA inspectors, human rights protesters and a group of art college students manning barriers Parisian style are all involved in a running battle in front of City Hall. Plum watches from City Hall roof as the twists and turns of his complicated plotting come together in farce and hilarity - with a one last sting in the tail.
