故事发生在一个名为迪斯科的异想世界之中。一年一度的Hogswatchnight即将到来，这是这个世界里最为盛大和隆重的一个节日。每逢此佳节到来，圣猪老爹（多米尼克·波雷里 Dominic Borrelli 饰）都会骑着野猪拉的雪橇，挨家挨户满足孩子们许下的愿望。然而这一次，圣猪老爹却似乎遇到了麻烦。
神秘组织派出了杀手Teatime（马克·沃伦 Marc Warren 饰）追杀圣猪老爹，因为后者的存在严重扰乱了这个循规蹈矩的世界的规律。Teatime绑架了牙仙（西妮德·马修斯 Sinead Matthews 饰），令所有孩子忘记了圣猪老爹的存在。在这个节骨眼上，死神（伊安·理查德森 Ian Richardson 饰）挺身而出接替了圣猪老爹的工作，与此同时，死神的孙女苏珊（米歇尔·道克瑞 Michelle Dockery 饰）也在努力的找寻着圣猪老爹的下落。

In series nine, chaos, paranoia and misunderstanding – yes, it's life as usual in the Harper household. Ben stands up to – and gets put down by – his own school bully and gets a little jealous as a rich business man falls for Susan – or is that Janey? There are new worries as they discover Michael's seeing a therapist and Ben fails his retraining exam – and, while the family is divided over mean Uncle Norris's inheritance and the acquisition of a puppy, Ben's delighted to discover he's the inspiration for a wealthy if unhappy, celebrity dentist!

In the eighth series, love is in the air in the Harper house. Ben is in love – with an extremely large television; Janey is in love with a new man; and Michael's current love has announced that she is pregnant. Meanwhile, Ben and Susan's credit card statement highlights each of their secret vices and an armed robbery at the local bank leads to Ben and Janey being taken as hostages. Michael and Alfie investigate the world of internet dating with mixed results and Abi realises her true vocation in life is to become a nun!

In the seventh series, a mystery man arrives asking for Janey – Susan finally discovers the identity of Kenzo's father. Roger and Abi's marriage announcement gives Susan the idea to renew her marriage vows despite protests from Ben. A death in the dentist's chair is not very good for business, but, as Ben discovers, it is not very good for your private life either. Michael succeeds in placing the whole family on The Weakest Link, but Anne Robinson raises more difficult questions than might have been expected.

In the sixth series, Janey and son Kenzo spend much more time at the Harper house than is good for Ben, and Micheal moves from scam to scam with alarming ease. Add to that the ever-so-slowly blossoming of the Abi-Roger romance and the new cuckoo in the nest, wiser-than-he-looks Alfie Butts and the problems multiply. The family's hurdles include Ben joining a secret society (The Brotherhood of the Cockerel), Suasn's new job leading her to a dinner date with a new man and an encounter with squatters. In other words, as usual, problems and situations constantly conspire to remind Ben and Susan that 'Family' is an 'F' word.

In Series five, Ben and Susan are enjoying some new-found tranquility, Nick has moved into his own flat, Janey is at university and Abi is usually out at evening class. Naturally the peace is not to last! Janey comes back home with baby Kenzo and Michael has been "born again" and is holding Bible study sessions in the living room. With Ben's famous dental patients, Susan's election ambitions and an unheathly obsession with Inspector Morse – not to mention the unlikely perils of house-sitting in a luxury modern apartment – domestic life is soon to be back to normal. So when Ben and Susan start being nice to each other it's no wonder Abi's suspicious; they could not be getting a divorce could they?
