As Tom Baker reached the end of his seventh season in Doctor Who, many changes were in store. Romana and K9 remained in E-space at the end of Warrior's Gate while Adric continued to travel with the Doctor. These three stories - The Keeper Of Traken, Logopolis and Castrovalva - saw the arrival of two more companions, Nyssa and Tegan, and the return of the Doctor's arch-enemy, The Master, as well as the transition from Tom Baker's Doctor to Peter Davison's. Packed with special features, including the only DVD commentary recorded by the late Anthony Ainley and possibly Tom Baker's most enlightening interview to date, this boxed set covers one of the most pivotal times in the show's history.
The Keeper Of Traken
The Doctor and Adric answer a distress call from the Keeper of the tranquil planet of Traken WHERE a living statue poses a deadly threat.
Logopolis
The Doctor's plan to enlist the help of Logopolis's mathematicians in repairing the TARDIS's chameleon circuit becomes sidetracked when the Master's interference leads to disaster on a universal scale.
Castrovalva
The Doctor's regeneration is failing, and his last hope rests with Nyssa and Tegan, who struggle to steer the TARDIS to the remote city of Castrovalva, renowned for its healing powers.
