The Invisible Enemy
The TARDIS encounters a huge, fibrous mass in space, and as it attempts to pass through the obstruction, a violent discharge from the central console knocks the Doctor out. He manages to set a course for a medical outpost, the Bi-Al Foundation. Barely able to explain the Doctor’s predicament, Leela leaves the Time Lord in the capable hands of Dr. Marius, a brilliant but eccentric pathologist (he has fashioned his portable computer in the shape of a dog and christened it K-9). But whatever affected the Doctor soon spreads to others at Bi-Al, and the Doctor is now clearly the center of a hive mind directing the actions of the infected. The fight to save the doctors and nurses at Bi-Al is a losing battle; the Doctor and Leela must take the fight to the source of the problem: inside the Doctor’s own body!
