Reginald 'Reggie' hates his cozy, well-paid but boring routine life as in Groomtech's department head of disposable razors. This time, crazy, power-hungry CEO Chris orders Reggie and his over-eager, half-wit sycophant assistants Anthony and Steve to come up with a novel use for pumice. Meanwhile Reggie's wife's feminist discussion group crowds him out of his own living room.

Reggie has another ghastly, boring day at the office. Loony boss Chris orders him to be more conventional, from small talk to carrying his empty briefcase. The latest shaving ideas are typically uninspired. Reggie's violent visions of eliminating people he knows now extend to his mother, a nagging champion presently obsessed with planning his dad's funeral.

Still dissatisfied with his lot Reggie considers that perhaps he would make a good teacher and goes to Nicola's school to give a talk about his work. This is surprisingly well-received and so he invites a school party to visit Groomtech. This,however,does not go according to plan. Perhaps he will not be a teacher after all.

Reggie's morbid hatred now extends even to his wedding witness, Monty. At work, he seizes CEO Chris's latest obsession, globalization, to organize a business trip to Helsinki with his sexy colleague Jasmine. Having just has a bad row with his wife, he plans meaningless adultery, but once that appears a real option gets cold feet. Then Chris turns up most inopportunely.

Reggie hoped riding a cool bike would relieve his anger about British Rail and his non-happening sex life (even now the spousal agendas don't clash, Nicola's period does), and bragged about it in advance, but that proves another painful experience. CEO Chris needs to learn about the company and deliver daunting promises to the board after a year of (mis)management. Reggie coaches him tirelessly, even during the weekend, but is deeply disappointed.

Reggie hopes to have solved his commuting train nightmare: a bicycle. His haughty claim to leave his fellow passengers forever is dismally retracted after aching all over where he didn't even realizing to have muscles. At work Chris's latest daft idea requires a speaker, and Reggie, the only one on staff showing no interest at all, is designated.

Whilst deciding against suicide Reggie sees himself at a crossroads and resigns from Groomtech,planning to lead a self-sufficient life growing his own vegetables. But money is tight,Nicola is fearful for her job and the best the Job Centre can offer Reggie is shelf-stacking. Mother is planning to marry Nicola's dad and the therapist is rubbish. With Groomtech facing their largest decrease in disposable razors in years and Chris begging him to return,should Reggie sacrifice his principles and once more chain himself to the capitalist life?

David, the accountant who has just moved in next door, comes to call on the Perrins,who bore him with their troubles. Reggie tries unsuccessfully to sell his home-made bread at the local farmers' market but Groomtech are also in trouble. Sales are slipping and Anthony is the reluctant occupant of Reggie's executive office. When Reggie decides to bite the bullet and ask to be reinstated he finds that Chris has been sacked and he has been made the new managing director.

Determining "not to lose touch with reality",Reggie makes sweeping changes,banning ties and introducing the wearing of slippers,a tea-lady and a bouncy castle to bounce ideas around in. He also gives strangers lifts in his company car. When the boss expresses disapproval Reggie changes the firm's name to Grot and announces that it will make only useless things. Nicola,now sacked,is bored at home,spending her time mending basket chairs, whilst her father tells Reggie he has cold feet about marrying his mother.

The staff express doubts as to the viability of Reggie selling his 'Grot' products - and indeed as to his sanity - but the goods fly off the shelves. The Groomtech chairman,hugely impressed,gives Reggie his next assignment,to cut half the staff. Nicola,feeling neglected as Reggie embraces his work with great enthusiasm,initially turns down David after he makes a pass at her at the swimming baths but still ends up ringing him. William,desperate to avoid matrimony,tries a feeble ploy to persuade Marion that he is gay,though it fails to work.

Reggie resists the board's efforts to make him conform and stalls when told he must sack a staff member,an announcement which sends Anthony and Steve falling over themselves to keep in with their boss. Told that Groomtech will ultimately be sold and he will be fired ,Reggie plots his revenge,including a naff and sexist advertising campaign featuring a leering Chris Jackson. He is so busy working on this he neglects Nicola and when he tries to make up for it with a birthday surprise,he ends up getting the surprise as he finds her in bed with David.

After setting to work on David's house with a nail-gun,Reggie moves in with Anthony in his chaotic flat and exposes Nicola's infidelity in his best man's speech at his mother's wedding. Groomtech is sold but nobody is sacked. However Reggie is demoted whilst Chris gets his old job back.Nicola comes to the flat where Reggie is enjoying the single life,to tell him that she now has a job and wants him to come home. Reggie is not certain if he even wants to stay in the country and,after Nicola has gone,packs a case.
