In the past, the Colonies had been at war with a cybernetic race of their own creation, known as the Cylons . With the unwitting help of a human named Gaius Baltar, the Cylons, now in human form, launch a sudden sneak attack on the Colonies, laying waste to the planets and devastating their populations . Out of a population numbering in the billions, only approximately 50,000 humans survive, most of whom were aboard civilian spaceships that avoided destruction . Of all the Colonial Fleet, the eponymous Battlestar Galactica appears to be the only military capital ship that survived the attack . Under the leadership of Colonial Fleet officer Commander William "Bill" Adama and President Laura Roslin, the Galactica and its crew take up the task of leading the small fugitive fleet of survivors into space in search of a fabled refuge known as Earth . </P> <Table> <Tr> <Th_colspan="2"> Season </Th> <Th> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td> Miniseries </Td> <Td> </Td> <Td> December 8, 2003 (2003 - 12 - 08) </Td> <Td> December 9, 2003 (2003 - 12 - 09) </Td> </Tr> <Tr> <Td> </Td> <Td> Season 1 </Td> <Td> 13 </Td> <Td> October 18, 2004 (2004 - 10 - 18) (UK) January 15, 2005 (2005 - 01 - 15) (U.S.) </Td> <Td> January 24, 2005 (2005 - 01 - 24) (UK) April 1, 2005 (2005 - 04 - 01) (U.S.) </Td> </Tr> <Tr> <Td> </Td> <Td> Season 2 </Td> <Td> 20 </Td> <Td> July 15, 2005 (2005 - 07 - 15) </Td> <Td> March 10, 2006 (2006 - 03 - 10) </Td> </Tr> <Tr> <Td> </Td> <Td> Season 3 </Td> <Td> 20 </Td> <Td> October 6, 2006 (2006 - 10 - 06) </Td> <Td> March 25, 2007 (2007 - 03 - 25) </Td> </Tr> <Tr> <Td> </Td> <Td> Razor </Td> <Td> Film </Td> <Td_colspan="2"> November 24, 2007 (2007 - 11 - 24) </Td> </Tr> <Tr> <Td> </Td> <Td> Season 4 </Td> <Td> 20 </Td> <Td> April 4, 2008 (2008 - 04 - 04) </Td> <Td> March 20, 2009 (2009 - 03 - 20) </Td> </Tr> <Tr> <Td> </Td> <Td> The Plan </Td> <Td> Film </Td> <Td_colspan="2"> January 10, 2010 (2010 - 01 - 10) </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Season </Th> <Th> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr>
