Dave Potts a quantity surveyor in the building industry is beaten about the head and dragged to the edge of the roof of a tall block of flats in an attempt to throw him over only to be saved in the nick of time. He is an intelligent person who has a flare for theories and stumbles on one for a remedy for rheumatoid arthritis. Being essentially an accountant to the building game it's not surprising he has confrontations with various people whose livelihoods depend on making money from contracts in a very competitive world. Despite this he always conducts himself in a reasonable and fair manner and is generally a likeable person. So who would want to attempt to take his life?
