After a harsh 200 years humanity was getting stable, everything was fine, until a war broke out and ruined everything. But still hope remains, there are humans who survived that great war, where for the first time in history, every participating nation had used neuclear bomb, desolating most of the planet. In these conditions, we follow the story of a submarine captain called Jakub, who was discarded from his submarine, by his lower workers. He landed on a beach of a destroyed city, the city where he was born. When he started looking for food and other things he meets a little girl called Angle, who reminded him of someone important. He now tries to protect her by any cost. He wants her to survive. So will humanity survive this calamity? Could they be "The Last One Remaining"?
