With the newly acquired knowledge of the seemingly invulnerable creatures’ weakness, grief-stricken Evelyn Abbott finds herself on her own, with two young teens, a defenceless newborn son, and with no place to hide. Now, 474 days after the all-out alien attack in the Abbotts summon up every last ounce of courage to leave their now-burned-to-the-ground farm and embark on a peril-laden quest to find civilization. With this in mind, determined to expand beyond the boundaries, the resilient survivors have no other choice but to venture into eerily quiet, uncharted hostile territory, hoping for a miracle. But, this time, the enemy is everywhere.
