While his 7-year-old son Aiden waits outside in his truck, Frank and an accomplice are attacked by an unseen creature. Aiden is also attacked but he and Frank survive the encounter with the creature and return home, where their condition worsens. Frank sets up a locked room and demands that no matter what, Aiden's older brother, 12-year-old Lucas, keep them locked inside. Three weeks later, Lucas spends his time roaming the town, collecting roadkill and killing small animals before taking them home.
