The people of Portwenn are concerned for Radio Portwenn's DJ Caroline Bosman, whose increasingly erratic behaviour has them suspecting that she has been hitting the bottle. The Doc has to deal with an elderly patient whose personal aroma can clear a room, but is unable to determine a medical cause for the stench. PC Mylow hopes that his pheremone spray will endear him to a pretty newcomer to the village, while the Doc/Louisa/Danny triangle gets even more complicated.
