While orbiting the planet Alfa 177, the U.S.S. Enterprise experiences a transporter malfunction when Technician Fisher is beamed up from the planet with some magnetic ore on his clothing. Scotty checks the transporter and finds nothing wrong, so Captain Kirk beams aboard. Kirk leaves with his officers and when the transporter room is deserted, a second Kirk materializes on the pad.

When a space animal is beamed aboard the starship and splits into two entities; one tame and one vicious, it is discovered that the same thing has happened to Kirk. While one Kirk is good and honorable, the other is evil and runs amok on his ship, committing violent acts, including the attempted assault of Yeoman Janice Rand.

Meanwhile, the transporter continued to split objects into two entities, thus forcing the remainder of the ship's landing party to remain on the planet's surface. Alfa 177's approaching night promises certain death from exposure and freezing temperatures to the unprotected landing party.

As time passes, the "good" Kirk is weakening, losing his ability to make decisions, while his "evil" half is dying. Neither Kirk can survive without his other half. Time is running out, not only for Captain Kirk, but for the landing party on the planet's surface.

Scotty effects repairs on the transporter, but there's no time to test it. McCoy is fearful because the "space dog" which had been split earlier, had gone through the repaired transporter and, while joined into one animal, was dead. Kirk takes the chance and beams down with his counterpart and returns to the U.S.S. Enterprise whole and alive. Quickly the landing party is beamed aboard, worse for the cold, but alive.

This second volume of episodes on DVD from the original Star Trek includes the popular and sexy "Mudd's Women," which introduces the character of interstellar huckster and fugitive Harry Mudd (Roger C. Carmel, later to return in another classic episode, "I, Mudd"). The Enterprise beams aboard Harry and three beautiful and scantily clad women whom the con man is carrying as cargo. The transport damages the starship, forcing Captain Kirk (William Shatner) to take a detour to a mining world for a supply of dilithium crystals. Harry uses the women as bait to get the miners to help him flee from the authorities--but a revelation about his liberal use of an attraction-enhancement drug adds a twist to things. This clever and novel installment in the series grafted the unlikely element of a petty, colorful crook onto a science fiction show, an obvious forerunner of Deep Space Nine's inclusion of Quark among its own major characters.

Also in this volume is another outstanding episode, "The Enemy Within." Written by renowned novelist-screenwriter Richard Matheson (The Incredible Shrinking Man), the story proposes a transporter malfunction that results in Captain Kirk being divided into two versions of himself, one aggressive and brutal, the other sensitive and good. Essentially, the personality mix that makes Kirk an effective leader and balanced man is scattered like so many marbles, and the result is one captain running around mauling women and wreaking havoc while the other is frightened and indecisive. The production is very effectively done, and Shatner's performance is among his most interesting. --Tom Keogh
