The Curse of Fenric is the third serial of the 26th season of the British science-fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 25 October to 15 November 1989. In it, the ancient evil force Fenric uses the vampiric Haemovores, descendants of humanity from the future, to attack a World War II naval base in England and orders them to destroy life on Earth by poisoning it with chemicals. Two further versions of this story exist: the 1991 video release incorporated about six minutes of extra material into the original narrative, and the 2003 DVD included a 'Special Edition' edited into a single movie-length feature, with new special effects, re-editing of some scenes, and 12 minutes of unbroadcast footage. Plot The Seventh Doctor and Ace arrive at a British naval installation near Maiden's Point on the Northumberland coast during World War II. The base contains a supply of nerve gas and the Ultima supercomputer used by Dr. Judson to decode German messages as well as Viking runes in the catacombs. The runes warn of Fenric, whom the Doctor recognizes as a being that can control his "wolves", individuals manipulated by his powers. The Doctor and Ace find a covert Russian squad attempting to steal Ultima. As Ace becomes smitten with their leader Captain Sorin, the Doctor warns them to lay low. Exploring the catacombs, the Doctor and Ace find a glowing Oriental vase among the Viking treasures, which is confiscated by the base commander Millington and given to Judson to study. As Judson places it within Ultima, he is struck by electricity and taken over by the spirit of Fenric. Fenric calls out to the Ancient One, a Haemovore in the nearby sea, who leads an army of Haemovores to attack the base and local residents, turning them into Haemovores. Ace warns Kathleen, a WRNS, to escape with her newborn child, Audrey. The Doctor sets up a chess problem, hoping to distract Fernic long enough to find a permanent solution to stop him. Sorin arrives and tries to kill Fenric but learns he is one of his wolves, a descendant of the Vikings that brought the Oriental vase here. Ace arrives, sees Sorin studying the chess board, and offers the solution. The Doctor arrives too late as Sorin reveals himself as Fenric, commanding the Ancient One to attack the Doctor. A psychic
