Episode Details

Battlefield

The Doctor and Ace arrive near the site of an archeological dig to discover strange goings on that have already attracted the attentions of UNIT, now commanded by Brigadier Winifred Bambera. Soon a battle between the mythological characters of Arthurian legend is raging, but why do they all refer to the Doctor as Merlin?

Ghost Light

Travelling back in time to Victorian England, Ace and the Doctor visit a house that Ace knew throughout her childhood as a haunted and frightening derelict. But what are the mysterious powers that have a grip on the people who live there, and what is the secret being hidden in the basement?

The Curse of Fenric

A small coastal village in wartime England is the setting. A historian discovers that an ancient curse has unleashed the Wolves of Fenric, and a number of the local residents have become Vampires. During their investigations they make some disturbing discoveries about Ace's past.

Survival

The Doctor and Ace return to Ace's old home, Perivale, where mysterious disappearances lead to the discovery of a race of catlike beings who can travel between dimensions. The Doctor fights to save Ace, who has been drawn into their web, and discovers that his old adversary the Master is already trapped.
