The second war against the Cylons is over, and The Twelve Colonies have been destroyed. Now Commander Adama of the Battlestar Galatica and President Laura Roslin lead a ragtag fleet of refugees in a supposed search for the fabled lost thirteenth colony, Earth. However, the dangers they face are many, which compound an already difficult situation. In addition to the Cylons hunting and attacking the fleet in space and their infiltrator units carrying out sabotage--even as their former unwitting pawn, Gaius Baltar, helps in the hunt for them while hiding both his own guilt and the strange presence that haunts his every thought--the fleet also faces internal political conflict in which the rabble-rousing figure Tom Zarek is merely the loudest dissenting voice, not to mention recurring shortages of food, water, and even oxygen. In the midst of these trials, however, clues begin to appear to suggest that Adama's bluff about finding Earth might hold more truth than anyone could have guessed.

The series is set 97 years after a devastating nuclear war wiped out almost all life on Earth. The only known survivors are the residents of twelve space stations in Earth's orbit prior to the war. The space stations banded together to form a single massive station named "The Ark", where about 2,400 people live. Resources are scarce and all crimes no matter their nature or severity are punishable by death ("floating") unless the perpetrator is under 18 years of age. After the Ark's life support systems are found to be critically failing, one hundred juvenile prisoners are declared "expendable" and sent to the surface in a last ditch attempt to determine if Earth is habitable again. The teens arrive on a beautiful planet they have only seen from space. Confronting the dangers of this rugged new world, they struggle to form a tentative community. However they discover that not all humanity was wiped out. There are people on Earth who survived the war, called "grounders" by the 100. The Ark consists of the space stations previously representing the nations of the UK, USA, Australia, Canada, China, Japan, India, Russia, Venezuela, France, Brazil, and Uganda.
