Every midnight someone is called to The Grounds, that's where people are buried alive. This is the government's solution to the rising human population. They eventually want only a certain amount of people to be living on the Earth, but burying people alive just wasn't enough for them, so they've released a deadly pandemic virus into the public to do it for them.
No one can trust anyone anymore. If you see someone on the streets, you have only one way of knowing if they have the contagious virus. Ivy and her sister, Willow, are the only ones left in their family. They're trying to survive by staying in the woods and keeping their distance from other people, until Ethan, a boy from Ivy's school, decides to join them.
The virus has spread everywhere now and people are still being buried alive. Together, they're determined to find safety. It's only a matter of time until one of them gets the virus or is called, and there's nothing they could do if they're buried six feet underground.
