Voyager is suddenly rocked by a distant explosion. Although ship systems appear undamaged, all information and control screens are suddenly locked and display an ominous
omega symbol.
Captain Janeway arrives on the bridge and instructs the crew not to worry. She orders the ship's computer to override the lockout and transfer all sensor data to her ready room, but leaves without explaining to her bemused crew what happened. After locking herself in her office she asks the computer to brief her on the detection of an object referred to as “Omega.” Janeway also summons
Seven of Nine, an ex-Borg member of the crew, to her ready room, as the
Borg have their own knowledge of “Omega.” Because
Voyager has been separated from
Starfleet, the Omega Team (a specially trained group which would normally be tasked with handling situations involving "Omega") cannot be brought in to deal with the problem. Janeway decides to break the code of silence involving the symbol and share information with her senior officers. She announces that a molecule hazardous to space travel, the Omega Particle, has been detected and she intends to follow the “Omega Directive,” an order that requires Starfleet captains to destroy Omega at all costs. Omega is unstable and the explosion of even one particle can render warp travel impossible forever for a vast surrounding region of space. Since it represents an existential threat to space-faring civilization, the need to destroy it warrants rescindment of the
Prime Directive. Moving to the coordinates of the explosion they encounter the planet and its resident alien race that created it. The society is on the brink of economic failure and is making Omega particles to “give their children a chance at a future.” Seven of Nine displays an interest in the scientists' methods, however, hoping to save the Omega particles and harness them because she believes them to be perfection—infinite parts working together as one (like the Borg)—despite ample Starfleet and Borg evidence of their incredible danger: The Borg, referring to the Omega particle as “Particle 010,” are expected to assimilate it at all costs, even though they have experienced the loss of a large quantity of Borg vessels to Omega particle explosions while trying to harness the power of the substance. Seven notes, furthermore, that the ability to harness Omega would make the Borg a nigh-unstoppable force; this remark only strengthens the urgency and motivates Janeway to wipe out all Omega particles, at any cost, as determined by the Omega Directive. Eventually and through a series of issues and difficulties, all the particles are safely gathered together and detonated a safe distance from the alien planet. Just before they are destroyed, they inexplicably stabilize, and Seven is able to view
perfection for 3.2 seconds, “an eternity worth.” ==Critical reception==
