"The Omega Directive" is the 89th episode of the American science fiction television series Star Trek: Voyager airing on the UPN network. It is the 21st episode of the fourth season. In this episode, Captain Janeway must undergo a top secret mission to destroy a molecule called an "Omega Particle" that the Federation has deemed too dangerous to be allowed to exist. Plot 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 relativistic 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—even the Prime Directive is null and void under such circumstances. As Janeway explains, Omega is unstable and even the explosion of one particle out in space can nullify subspace for many light years around it, rendering faster-than-light travel impossible within that area. 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
