Where to Watch K-9 and Company: A Girl's Best Friend (1981)

Summary

Sarah Jane Smith returns to Earth and carries on with her journalist career. Now, in 1981, she has managed to rebuild her career and has come, a matter of days before Christmas, to her Aunt Lavinia's (a famous scientist) house in the sleepy English village of Moreton Harwood to write a book and to rest after her world-travelling assignments. However, her journalist's nose sniffs out another mystery when she arrives to find Aunt Lavinia gone, and nobody knows where she is, but the local rumour is that she was the victim of a local witch coven.
