Family man Keith Amery goes camping on the moors alone and sees a helicopter land but falls and hits his head, bringing on amnesia. On the advice of Eddie's old psychiatrist, Keith's wife asks Eddie to help Keith recall events, but with little success. Simultaneously, an Australian girl named Denise arrives at Radio West, claiming to be a presenter seeking tips from Eddie. Whilst Eddie is occupied with Denise, her associates track down and abduct Keith.
