The world as we know it has come to an end, due to a rain-carried virus that wiped out nearly everybody in Scandinavia. Six years after that event, two Danish siblings emerge from the safety of the bunker where they have been staying. After discovering all remnants of civilization gone, they join a group of fellow young survivors, and together they head out on a danger-filled quest throughout the abandoned land in search of signs of life. The survivors think they have been set free from societal rules of the past, but they quickly find that even in a post-apocalyptic world there is love, jealousy and other coming-of-age dilemmas that young people have always faced.
