The Johansson family—mom, dad, their rebellious teenage son, and young daughter—are looking forward to a quiet summer in their idyllic suburban town. But in the blink of an eye, things go from blissful to berserk when a horrifying plague tears through the community. After a string of grisly deaths, the government puts the neighborhood on lockdown. But one thing soon becomes terrifyingly clear: you can't quarantine the apocalypse. This nightmarish, blood-soaked shocker establishes sharply drawn, recognizably real characters—and then watches what happens when they're put through the wringer to survive.
