Season 2, episode 7. The Enterprise is at Pyrus VII. Sulu, Scotty & Crewman Jackson has beamed down to investigate. The Enterprise has lost contact with them for awhile but Jackson communicates he is ready to beam aboard and when he does, he is dead. A strange voice is heard coming from Jackson so Kirk, Spock and Bones beam down to find out what is going on and what has happened to Sulu & Scotty. When the 3 beam down, they see thick fog, 3 witches, an eerie castle and a black cat upon entering the castle. They meet Korob & Sylvia, end up in a dungeon and find that Scotty and Sulu are in a trance of sorts and obeying the will of the two sorcerers. The sorcerers use their magic against the Enterprise, Bones ends up in a trance-like state while Kirk & Spock try to figure out a way to beat the sorcerers and save their ship & crew. Sylvia becomes very cruel and disputes with Korob. Korob decides to help Kirk and his crew because he feels that Sylvia is going way to far.

One of those "fun" episodes. It first aired just before Halloween in 1967... it really does make a great Halloween show. I still love this episode even though it is not as popular nor rated as high as some of the others.
