<title>Battlestar Galactica 1978 Dvd3 e09 e10 e11 e12 [NL] [FR] [ENG] Sub</title>
<description>
<![CDATA[In een afgelegen zonnestelsel leeft een mensenras op twaalf koloniewerelden. Ze zijn al eeuwen in oorlog met de Cylons, gevechtsrobots die ooit werden gemaakt door een allang verdwenen buitenaards reptielachtig ras. Met de hulp van de menselijke verrader Baltar zijn de Cylons erin geslaagd de mensheid vrijwel uit te roeien. Slechts een oorlogsschip kan aan de vernietiging ontkomen: de Battlestar Galactica van commandant Adama.
Met een vloot burgerschepen vol vluchtelingen vlucht de Galactica voor de Cylons. Adama besluit op zoek te gaan naar de legendarische 13e en laatste kolonie, genaamd Aarde. Tijdens de lange en gevaarlijke reis worden ze voortdurend bedreigd door de achtervolgende Cylons en andere gevaren.]]>
