Battlestar Galactica continues from the 2003 mini-series to chronicle the journey of the last surviving humans from the Twelve Colonies of Man after their nuclear annihilation by the Cylons. The survivors are led by President Laura Roslin and Commander (later Admiral) William Adama in a ragtag fleet of ships with the Battlestar Galactica, a powerful but out-dated warship at its head. Pursued by Cylons intent on wiping out the remnants of the human race, the survivors travel across the galaxy looking for the fabled and long-lost thirteenth colony: Earth.

A former spy uses his Special Ops training to help people in need.
