The premise, which is summarized by kid, is that aliens have invaded the earth a year before. They first disabled all of our technology and killed off ninety-percent of the human population. Now a group of three hundred people try to survive--and fight them--along the East Coast. The main character is Tom Mason (Noah Wyle), a former college professor, and his sons. One is a young adult and is one of the soldiers, the youngest is ten-years old and wants things to be how they used to be before the aliens came, and the third is being held captive. They want to rescue him--and actually see him--but he's attached to this organic-looking contraption called a harness, which the spider-like aliens use to control them.
Other characters are potential love interest Dr, Anne Glass (Moon Gloodgood of TERMINATOR: SALVATION) and group commander Captain Weaver (Will Patton portraying the usual asshole-character).
The first two episodes are fast-paced, interesting and entertaining, though it adds nothing new to the alien invasion sub-genre. It borrow from everything that's come before it, from WAR OF THE WORLDS to INDEPENDENCE DAY to THE TRIPODS. The show itself has the same look/feel as THE WALKING DEAD television series, with aliens replacing the zombies.
