Doctor Who Story 081 Planet of Evil by David Maloney (1975)
4 March 2008A classic Tom Baker Doctor Who with Elisabeth Sladen as his companion. This one has elements of both Forbidden Planet and Dr. Jekyll and Mr. Hyde, and really has 4 enemies that the Doctor must Deal with or befriend. This is a great one, and I love the planetary sets as well as the space ship they end up on. Not only that but Sladen was so much more an equal to the doctor than Billie Piper could ever be. This is must see for all Tom Baker fans.
The TARDIS picks up a distress call, and ends up on the planet Zeta Minor, where a Morestran Scientific expedition had fallen to an invisible killer that takes the bodies and then brings them back completely drained of life. A military mission from Soresnosn arrives, and finds Professor Sorenson (Frederick Jaeger) still alive, though a bit manic and unwilling to give up his antimatter work. The squad takes the Doctor captive, thinking he is the killer, and beam the Tardis to their ship with Sarah Jane Smith (Elisabeth Sladen) inside of it.
REVIEW CONTAINS SPOILERS…

The killer turns out to be an antimater creature, who came from a pit where Sorenson took rock samples. The ship Commander Salamar (Prentis Hancock) is becoming unstable and won’t listen to his second in command Vishinsky (Ewen Solon), nor the Doctor, and they take off, but Sorenson hid Ant-Matter samples on the ship, so the ship starts to get dragged back towards the planet. Sorrenson becomes an Antiman, and starts attacking the crew, and killing them, and he starts turning into multiple anti-matter creatures because of an attack Salamar used which made him more powerful.
Eventually Vishinsky takes over, and helps the Doctor, so he can go and get Sorenson, and he takes him to the planet, and puts him into the antimatter pit, stopping the creatures on the ship and allowing it to fly again. The pit releases the now cured Sorenson and the Dcotor takes him back to the ship, and gets Sarah Jane, and they take off.

An enjoyable story for sure.
