"The Cylons were created by man."
They were created to make life easier on the Twelve Colonies
And then the day came when the cylons decided to kill their masters.
After a long bloody battle an armistice was declared.
A remote space station was built...
...where Cylon and Human could meet and maintain diplomatic relations.
Every year, the colonials send an officer.
The Cylons send no one.
No one has seen or heard from the Cylons in over forty years."-Intro Captions
Part 1 Edit
After a long and bloody war known as the First Cylon War between the Twelve Colonies (the homeworlds populated by humans) and the Cylons (human-created robots who rebelled against them), an armistice was signed. The Cylons left Colonial space and avoided all contact with humankind for 40 years, up until the events depicted in the miniseries and, later, the first season (and all that followed).
The Battlestar Galactica, an aging Battlestar (battleship/carrier hybrid warship) under the command of Commander William Adama that had fought in the First Cylon War, is being prepared for decommissioning and conversion into a museum. For this, her starboard flight pod has been closed off and converted into a museum and a squadron of old Viper Mark II fighters installed for display. The Colonies' Secretary of Education, Laura Roslin (Mary McDonnell) arrives on the passenger transport Colonial Heavy 798 to attend the decommisioning ceremony - Adama's son, Captain Lee Adama, reluctantly arrives as well to participate in the ceremony, having held a grudge against his father for some time prior to the events of the miniseries due to the death of his brother, Zak Adama, during a training exercise as a pilot.
The Cylons launch a surprise assault intended to exterminate the human race. Virtually all of the population of the Twelve Colonies are wiped out from extensive nuclear bombing on all colonies. Almost all of the Colonial Fleet's defensive units were disabled due to a backdoor in the new Command Navigation Program, a relatively new operating system now in widespread use among Colonial ships civilian and military alike, which left ships vulnerable to Cylon infiltration. The backdoor was introduced by Number Six (Tricia Helfer), a Cylon humanoid in the form of a human woman; she seduced the famous scientist Dr. Gaius Baltar (James Callis) and exploited their relationship to add a secret backdoor to the as well as complete access to all Colonial Fleet systems and information under the cover of an insider contract bid.
During her decades of colonial service, the Galactica's computer systems had never been networked, nor had the offending CNP software ever been loaded into memory. Thanks to this, the Galactica is unaffected by Cylon sabotage, allowing it to survive while the remainder of the fleet is decimated by Cylon forces, having been shut down before being able to respond. However, Galactica also supported a modern, CNP enabled squadron of Viper Mark VII fighters, all of which were disabled and promptly destroyed by Cylon forces; the Raptor accompanying them, crewed by pilot Sharon Valerii, callsign "Boomer", (Grace Park) and ECO Karl C. Agathon, callsign "Helo", (Tahmoh Penikett) is damanged in the engagement and is forced to land briefly for repairs on the planet Caprica. A group of survivors notice them; they offer to evacuate a small group of survivors, mainly children along with three randomly-selected adults. Helo, noticing Baltar in the crowd, decides to remain on the stricken planet, giving up his seat to evacuate Baltar, whom he believes to be of more use to the surviving human race than a mere Raptor ECO. Meanwhile, back aboard the Galactica, Its commander, William Adama (Edward James Olmos), assumes command of the few remaining assets of the Colonial Fleet; he decides to make an FTL (Faster-Than-Light) jump to the Ragnar Anchorage, a military armory station where the Galactica can resupply itself with weaponry and essential supplies to get it back into fighting shape.
Meanwhile, aboard the passenger transport vessel Colonial Heavy 798 now departing Galactica after the ceremony's conclusion, word is recieved about the widespread attacks on the Colonies. An automated message is recieved stating the initiation of 'Case Orange' - that most of the government has been incapacitated and that all remaining government officials should report in - Laura Roslin is soon sworn in as President of the Twelve Colonies after it is confirmed that the President and most of the government have been killed (Roslin is 43rd in the Colonial government line of succession). They are found by Cylon forces, who are fooled into believing its destruction after Lee Adama (who was escorting the vessel on its return journey) uses an onboard EMP generator from Galactica to create an EMP wave, mimicking a nuclear blast. The government starship carrying her (Colonial One) manages to assemble a group of surviving civilian ships.
Part 2 Edit
The Cylons soon locate the human civilian fleet; Roslin is forced to order all of the ships capable of faster-than-light (FTL) travel to jump immediately to escape; unfortunately, this means abandoning many of the survivors who are stuck aboard ships without FTL drives; as Roslin and the FTL ships jump away, the Cylons destroy the remaining ships
At the Ragnar Anchorage space station, Adama is attacked by a supposed arms dealer who claims to be simply bootlegging supplies, but who is clearly being affected by the radiation cloud surrounding Ragnar, which humans are immune to. Adama deduces that he is facing a new type of Cylon that looks, sounds, and acts human.
As the civilian fleet joins the Galactica at Ragnar, President Roslin appoints Dr. Baltar, who has not disclosed his suborning by the Cylons, as one of her scientific advisers to combat the Cylons. Number Six reveals herself to Baltar in hallucinatory form while attempting to direct his behavior. She suggests that she may have planted a microchip inside Baltar's brain while he slept, allowing her to transmit her image into his conscious mind. Responding to one of her suggestions, he is compelled to identify Aaron Doral, a public relations specialist, as a Cylon agent masquerading as a human. Despite his protests and the lack of any evidence to support the accusation, Doral is left at Ragnar when the Galactica departs.
As the Cylons blockade Ragnar, the Galactica and its fleet of Vipers engage the Cylon fleet in order to allow the civilian fleet to escape by "jumping" to a distant, unexplored area outside of their star system. The Galactica and the colonial fleet make good their escape. Adama then attempts to lift the morale of the surviving humans by announcing plans to reach a legendary thirteenth colony called "Earth", whose existence and location have been closely guarded military secrets. Roslin is skeptical and later confronts Adama and makes him admit that Earth is simply an ancient myth.
Returning to his quarters, Adama finds an anonymous note has been left for him stating "There are only 12 Cylon models." On Ragnar, Doral clearly appears to be suffering from radiation poisoning that has been shown to affect only Cylons. His identity as a Cylon is confirmed when a group of Cylons, including the metallic Cylon Centurions and several humanoid Cylons consisting of multiple copies of the Number Six, Doral, and Ragnar arms-dealer models, come to retrieve Doral. In a twist ending, one of the group appears to be Boomer, indicating that her counterpart on the Galactica is a Cylon as well.
