London, The mid-sixties. In what appears to have been a murder attempt, Britain's greatest pop sensation 'Vic Vox' has been left a foot tall - the effects of the 'shrink drug' administered by assailants unknown. Detective Chief inspector Ladyshoe and his team at Scotland Yard are out to find who did it, and why, but they are up against the clock. They need to crack the case within the week and return Vox to full-size in time for him to perform as the main act on television's biggest one-off, live pop show: 'Ready For Pop'.
