Cold Station 12

"Cold Station 12" is the fifth episode of the fourth season of the American science fiction television series Star Trek: Enterprise, the eighty-first episode overall. It was directed by Mike Vejar from a script by Alan Brennert, and aired on November 5, 2004, on UPN. It comprises the middle-act of a three-episode arc, preceded by "Borderland" and followed by "The Augments".

The series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, after leaving Enterprise stranded, Doctor Arik Soong and his Augments travel to "Cold Station 12", a secretive pathogen and bio-medical facility run by Starfleet Medical and the Denobulans, where much of this episode's plot unfolds. Once inside, they begin torturing the scientists with the goal of retrieving some 1,800 augmented embryos, allowing them to expand their race.

The production team created several new sets to represent the space station itself, as well as re-using some from "Borderland" to represent the Klingon starship. The make-up team were required to make Brent Spiner look younger for flashbacks and to show the progression of a character's exposure to a number of pathogens. The story-arc has been considered one of the best seen in Enterprise, and critics praised "Cold Station 12", specifically for the special effects and character development, but felt that the death scene crossed the line. On first broadcast, the episode was watched by 2.1 percent of the population according to Nielsen ratings, placing it in fifth position for the timeslot.
