But an ancient, dying race sees this human outpost as a last hope for survival...and millionaire Walter J Matheson III sees it as a marvelous business opportunity. When the Doctor and Peri arrive they find a fractured society dependent on film and TV. They also discover that the Republic's greatest entrepreneur is in league with one of the Doctor's oldest enemies. If they can't unravel the link between the two, they could end up in the deadliest soap opera of all time...
