    special,but good episode.
    As a landing party surveys a planet, a transporter malfunction splits Kirk into an aggressive aspect and a timid one. The aggressive Kirk threatens the security of the ship and crew, while the passive one tries to maintain his sanity and ability to command. In the meantime, the cause of the transporter problems haven't been determined, stranding Sulu and the team in the planet's subfreezing night temperatures while the two sides of Kirk's personality fight for control of the Enterprise.

    a very good story.
    but very special.
    a bit average,but very good acting too.
    for that years it are very good effects.
