The sun is slowly fading and the planet Earth is no longer blue. There is only one city left, and the last human community survives in it. People live in it with the knowledge of the inevitably ending end. In the shadow of the weapon.
 In their desire for immortality, they carry out genetic transformations or try to preserve the forgotten art of reading and writing and leave a message about people's ages.
 Beyond the city lies either the toxic masses of the ocean or the wild dark jungle inhabited by monsters and mutants. The only way is the river and on it lies Ostrov, a prison colony. Uncomfortable and rebels are sent here. In the transport of convicts is also Stefan Advani, a scholar, prisoner, outlaw and chess player, one of those who is trying to break the bars of the cage of souls.
 This is the story of him and the end of civilization. The new heirs of the Earth are coming.
