In the episode, the archaeologist River Song (Alex Kingston) summons the alien time traveller the Tenth Doctor (David Tennant) to a planet-sized library in the 51st century, where thousands of visitors disappeared without a trace a hundred years earlier when the library was shut off. The episode establishes that River Song has met the Doctor on many occasions but at this point in his life the Doctor does not recognise her.
The Hugo Award-nominated episode is also significant for introducing the character of River Song, who went on to play an important role in future stories.
