Synopsis

The Tenth Doctor takes Donna Noble to a planet-sized library in the 51st century. They find it empty of human life, with countless other living beings. An information kiosk warns them to "count the shadows". An archaeological expedition arrives, lead by the mysterious Professor River Song, who brings the cryptic last message sent from the library: "4022 saved, No survivors".
