A major cyberattack cripples the U.S., prompting estranged friends to gather at an off-the-grid home in an attempt to escape rising social unrest in this apocalyptic thriller. Years ago, James (Adrian Grenier) sensed that society was on the verge of collapse. In a bid to be proactive, he moved his family, including his wife Lily (Kerry Bishé) and their young daughter, to a secluded Northern California home. There, thanks to solar panels that power their home and fertile gardens to provide sustenance, James and his family learn to become self-sufficient. Then one day, seemingly out of nowhere, a viral text message with the subject 'Goodbye World' attacks utility services, plunging the entire country into darkness. When James' old college friends turn up on his doorstep, he welcomes them with open arms. But it isn't long before their comfortable sense of community begins to grow sour, and with martial law declared, an unknown future pushes tensions to the breaking point.
