All ten episodes from the US sci-fi drama following the aftermath of an alien invasion. Six months previously the Earth suffered an extraterrestrial attack on a global scale, which left only ten percent of the human population alive. Now soldiers and civilians are banding together in an attempt to fight back. Former university professor Tom Mason (Noah Wyle) is made second-in-command of the Second Massachusetts and must put all his knowledge of military history to the test to aid the cause.

The episodes comprise: 'Live and Learn', 'The Armory', 'Prisoner of War', 'Grace', 'Silent Kill', 'Sanctuary: Part 1', 'Sanctuary: Part 2', 'What Hides Beneath', 'Mutiny' and 'Eight Hours'.
