The first Cylon war has been raging for 10 years and a young Ensign William Adama joins the fleet. He's disappointed not to be assigned to a fighter but to a freighter. His co-pilot, Lt. Coker Fasjovic, isn't too keen on having a rookie flying his aircraft as he has only a short time before he again becomes a civilian. Their cargo is a civilian scientist, Dr. Becca Kelly, but they no sooner leave than she has new orders for them and a new destination. She is less than forthcoming about just what her secret mission is but Adama is keen, particularly as it involves going into Cylon controlled space. Nothing is as it seems however.

When a mysterious object crashes to Earth, a group of seemingly unconnected strangers die from the energy pulse, but then awaken to learn that they have assigned the task of preventing the impending Apocalypse.

When an old enemy, the Cylons, resurface and obliterate the 12 colonies, the crew of the aged Galactica protect a small civilian fleet - the last of humanity - as they journey toward the fabled 13th colony, Earth.

A re-imagining of the original series in which a "rag-tag fugitive fleet" of the last remnants of mankind flees pursuing robots while simultaneously searching for their true home, Earth.
