This release collects every episode from the fourth season of Falling Skies, the long-running series that takes place in the aftermath of an alien attack that left Earth a shell of its former self. Led by Tom Mason (Noah Wyle), a history professor, a group of human survivors who call themselves 2nd Massachusetts band together to make a stand against the alien invaders.

The third season of Falling Skies picks up just seven months after the 2nd Mass devastated Charleston, South Carolina, upon their arrival. With Tom having been elected to political office in the interim, the resistance continues to mount whatever opposition they can to keep the alien invaders from gaining full control.
