A diagram on a computer screen shows the descent of the capsule into the depths of the planet. And the black hole is supposed to be a mighty demon. As the base starts to quake and tremble, Jefferson rushes over to a door and opens it. Come on! Finished. Impossibly old. It begins to open. OOD (as one): We are the Legion of the Beast. ROSE (CONT'D): Doctor, the TARDIS is in there. ROSE: That's a black hole. She starts to head back to the base. THE DOCTOR (addressing the Ood): He is awake. THE DOCTOR (striding into the middle of the room): Oh, it's a sanctuary base! THE DOCTOR: The drill. TOBY: But who are you? TOBY: If... The Doctor and Ida stare down into the pit, horror struck as the Voice of the Beast laughs terribly. The Ood are serving. The Ood stands a few feet away from the two of them, and the communication orb suddenly shoots out and attaches to the crew member's forehead. The graphics on the computer screen indicate the part of the base that has been lost. The planet's moving! The smile fades from Toby's face. They're basically a herd race. What's going on??

Summary: The Doctor and Rose arrive on a base on a planet which is impossibly orbiting a black hole . The crew of the base, who are there on an expedition to drill to the middle of the planet, is led by Captain Zachary Cross Flane. A race of aliens known as the Ood serve them. A quake strikes the planet, causing several sections of the base, including the one where the TARDIS was, to fall into the planet. As the drill nears the planet's centre, the Ood begin foretelling the awakening of a " Beast ", which possesses archaeologist Toby Zed and later the Ood. The drilling finishes, and the Doctor offers to go with Ida Scott to the depths of the planet, where they discover a disc with unreadable markings found on the base and the possessed Toby's face. The Doctor believes the disc to be a door, and as it begins to open the possessed Toby tells Rose that the planet has begun to fall into the black hole and the voice of the Beast announces that he is free.
