but the ship jumps to warp speed. Archer brings the survivors to Sickbay, and finds their situation reminiscent of a Zefram Cochrane story he remembers (relating to first contact). The assimilated crew soon awaken, and in the ensuing melee Doctor Phlox is infected with nanoprobes. They escape, and Lieutenant Reed then finds them modifying ship's systems, and learns that the Enterprises phase pistols are ineffective against them. Archer, left with no other options, orders the section to be de-pressurized. Reed then begins upgrading the pistols, while Phlox treats himself with "omicron radiation" to destroy the nanoprobes. Enterprise again catches up with the transport, but the recent modifications suddenly activate and shut down weapons and propulsion. Soon after the aliens hail Enterprise and demand that they surrender, noting that "resistance is futile". In response, Archer and Reed board the ship with upgraded pistols, plant explosives, and beam out. Commander Tucker troubleshoots the alien modifications thereby restoring main power to Enterprise. With the transport crippled, Archer realizes the altered crew members are too far gone and orders the transport's destruction. Later, a recovering Phlox informs Archer that while infected he kept hearing a repeating numerical sequence - Earth's coordinates sent somewhere into the Delta Quadrant. Sub-Commander T'Pol states it would take almost 200 years to reach its destination, but Archer remains troubled, fearing they only postponed the invasion. Production Principal photography took place between February 27, 2003 and March 8. The B unit shoot for the episode was not completed until March 11. This coincided with the commencement of filming on the following episode, "First Flight". The Borg in the episode were all played by stuntmen who had previously worked on Enterprise, with four main "Stunt Borg" and four additional Borg for background shots. Bonita Friedericy was cast as Rooney, one of the researchers that discovered the aliens. Friedericy got the audition through her agent, director David Livingston and the casting assistant did not know that she was married to Billingsley, and producers Rick Berman and Brannon Braga did not let on that they had met her before. Friedericy did not share any scenes in the episode with her husband or film on the same days. Billingsley had suggested at one point during the filming of Enterprise that Friedericy should play all of his in-character wives. Director David Livingston is one of the more prolific Star Trek directors, and directed two other
