When Captain Kirk and his landing party arrive on Pyrus VII, they are met by eerie mists, a dark castle, wailing witches, zombies and a black cat. They soon learn that they are under the influence of a wizard, Korob, who tries to bend them to his will. They also soon learn that the black cat they saw is more than she appears and is in fact a powerful witch in her right. This beautiful witch, Sylvia, who wears a diamond pendant on her black dress, explains that they are explorers from another galaxy. However, Kirk and Spock must find a means to escape their grasp before they return to the Enterprise. Written by garykmcd

A weird and mystical offering from Star Trek !!!
16 September 2019 | by elo-equipamentosSee all my reviews

Developed as an outright and ultimate Science Fiction, this episode sails on mystic subject when Enterprise's crew has making a searching to unknown rocky planet, actually two aliens from an upper civilization desire becomes like humans with strange behavior to taste all lower feelings of the earthlings, the male one helps ours friends to escape from this nightmare, the final sequence with aliens is easy noticed the wires that holds the tiny puppets, enjoyable and a little oddity that makes Spock lift their eyebrows !!!
