S7-E4 The Power of Three



As the Doctor investigates reports of strange creatures haunting a London school, he encounters an old friend and her faithful robot companion. Meanwhile, Rose learns a few harsh truths from her predecessor about travelling with a Time Lord. Anthony Head guest stars, and Elisabeth Sladen, who accompanied Jon Pertwee and Tom Baker's Doctors in the 1970s, reprises her role as journalist Sarah Jane Smith.
