Long before the farm burned and the blue line was drawn, the Chenoweth family's quiet life was unraveling in ways they never imagined. Strange happenings started subtly—electrical devices glitching, animals acting restless, and whispered voices caught in the wind. Maggie, a dedicated veterinarian, noticed the subtle shifts in nature's behavior but couldn't yet grasp the full scope of the danger approaching.
James, struggling to hold the family together, grew increasingly distant as secretive government agents trailed their every move. Their daughter Meryl wrestled with an unsettling feeling of being watched, while young Arlo's curiosity led him to explore the dense woods nearby—where he stumbled on things no child should ever see.
When Arlo found an injured stranger in the forest—a man named Harbinger, carrying knowledge of an alien invasion and hunted by a ruthless extraterrestrial assassin—the Chenoweths were thrust into a nightmare that threatened to consume them all. As the fabric of reality tore open, a mysterious figure called McNab appeared, drawing the fateful blue line around their land—a containment field meant to trap the alien horrors but also sealing their fate. Betrayals, sacrifices, and unspoken truths would soon ignite a chain of events that pushed the family and the survivors into a desperate fight for survival, setting the stage for the horrors to come. After being between life and death, many of people who survive, got the Serum and left the farm, only to discover that there are many more assassins than expected.
