Razor takes place during the first thirty days of
Lee Adama's
Pegasus command during the period originally covered in the second half of season 2, after the episode "
The Captain's Hand" but before "
Lay Down Your Burdens", and uses flashbacks to show Rear Admiral Cain's orders during and shortly after the
Cylon attack, as well as events occurring on the final day of the first
Cylon War. Cain's actions in the wake of the holocaust are connected to the present by Kendra Shaw, self-described as Cain's legacy. Events of the final day of the first Cylon war follow Lieutenant
William Adama, a Viper pilot and Helena Cain, a child. Flashbacks of Adama discovering a lab housing the early Cylon experiments on humans as well as the
first Cylon hybrid and Helena Cain abandoning her little sister during a Cylon invasion of Tauron finish as the first Cylon war ends. Each character is left hanging somewhat (Adama is unable to free the surviving prisoners and Cain cannot find her sister). These are shown to be driving forces for their actions as the show continues. Cain goes on to teach Shaw that you have to become a 'razor' to survive during war while referring to her pocket knife, which later becomes Kendra's and then is passed on to
Kara Thrace at the end of the film. Admiral Adama teaches his son Lee a different lesson: that they cannot become butchers. Lee Adama's priority as
Pegasus commander is to restore trust and integrity to the troubled command, while preserving some continuity in the leadership that had evolved under Rear Admiral Cain. He picks Kendra Shaw as his
executive officer, promoting her to major, despite the stark contrast between Cain's enthusiastic praise and subsequent
Pegasus officers' complaints about Kendra's performance. First boarding
Pegasus less than an hour before the Cylon attack on the colonies, Shaw follows Rear Admiral Cain's order to make a "blind jump" that saves the ship from destruction at Scorpion Fleet Shipyards. Like Gaius Baltar on
Galactica, Kendra discovers that the Cylons were about to infect the
Pegasus with a computer software virus which would have disarmed
Pegasus and left it helpless. After
Pegasus receives reconnaissance information that all the colonies have been destroyed, Cain delivers a rallying speech inciting the crew to war for the purpose of revenge. The crew responds by chanting "So say we all!" throughout the ship; the Number Six Cylon agent
Gina Inviere awkwardly joins in. Lee Adama's first mission as commander of
Pegasus is a mission to retrieve a lost science team. Antiquated
Cylon Raiders from the first war appear and attack
Pegasus. Simmering bitterness between Kara and Shaw is exacerbated when Shaw endangers Kara and her wingman to defend the battlestar. Both pilots land safely, though Kara has to destroy a Raider that follows her into
Pegasus. During a heated exchange, Shaw reminds Kara that defying authority is a risky proposition aboard
Pegasus, recalling how Cain shot her executive officer, Colonel Jurgen Belzen, for refusing an order to attack a Cylon staging area filled with an unexpectedly strong force of Raiders. It is during this mission that Gina Invierre helps Cylon centurions board the
Pegasus and Shaw discovers Gina's true identity. It is hinted that the torture inflicted on Gina at Cain's orders had been influenced by the burgeoning romantic relationship between the Cylon and Cain. When Shaw is promoted to captain by Admiral Cain, she reminds her troubled protégé the Cylon tricked them all. Viewing the wreckage of the raider,
Sharon Valerii notes that Cylon lore tells of a group of original
centurions left to guard the first Cylon hybrid. This group, referred to as 'The Guardians', has been missing since the First Cylon War. Admiral Adama then recalls his rookie mission as a Viper pilot, when he encountered that hybrid and saw what the Cylons did to their human captives for their research. Admiral Adama concludes that the Cylons must still be pursuing the experiments, with the captured science team as new test subjects. Lee Adama approves a plan to use
Pegasus to find the basestar and lure the Cylon Raiders away from it, then launch a rescue team—including Kara Thrace and Kendra Shaw—outfitted with a nuclear warhead, in a Raptor. Admiral William Adama transfers his flag to
Pegasus to counsel his son on his first command. The diversion succeeds; the rescue team sacrifices its Raptor and boards the basestar. As the rescue team searches the basestar, the Cylon hybrid can be heard speaking in more coherent phrases than its more-modern counterparts. It repeatedly utters the words "All this has happened before and will happen again". The hybrid also makes a far more elaborate pronouncement, The science team is found and partly rescued, but the team comes under fire from Cylon centurions. While the team manages to evacuate the basestar in a second Raptor, the nuclear warhead is damaged and has to be detonated manually. Wounded, Shaw remains behind to detonate the warhead and comes face to face with the Cylon hybrid. The hybrid offers absolution to Kendra, who is haunted by the fact that it was she who fired the first shot in the massacre aboard the civilian ship called
Scylla as part of an operation to conscript civilians for the
Pegasus. The hybrid then tells her that "Kara Thrace will lead the human race to its end. She is the herald of the apocalypse, the harbinger of death. They must not follow her". Shaw tries to relay this information to Lee Adama but is stopped when the Cylons jam communications. Her final act is to detonate the nuclear warhead, destroying the basestar. On
Galactica, Admiral Adama reflects on Cain's legacy and proposes a posthumous commendation for Kendra Shaw, over his son's protests that she and other members of Admiral Cain's crew "butchered innocent civilians". They close their arguments noting that history's first draft will be written in their logs and Lee agrees to consider the commendation. == Cast ==
