Two great K-9 stories in one classic collection! In the four-part story, The Invisible Enemy, the Doctor (Tom Baker) answers a distress call from a shuttle crew infected with an intelligent virus. After the Doctor becomes contaminated as well, clones of the Doctor and Leela (Louise Jameson) are created to fight the virus. The first Doctor spin-off, K-9 and Company showcases the Doctor's two companions, Sarah Jane (Elisabeth Sladen) and robot K-9 (voice of John Leeson), as they attempt to solve a bewitching mystery. Extras include audio commentary with actors Louise Jameson and John Leeson, deleted scenes, and much more. Digitally remastered.
This is item 37 in The Doctor Who: The Fourth Doctor, Tom Baker (1974-1981) Series.
