A young woman wakes up in the basement of a man who claims he saved her life after pulling her from her overturned car which violently crashed along the highway. The man states that the world above them is no longer safe and is now a danger zone that threatens the rest of humanity. With no knowledge of what actually lies above and trust running thin between them, the woman questions what’s true and what’s not. Is the man a delusional psychotic that has a more sinister agenda for her? Or is it really hell on earth above ground like he swears?
