In a world where stone slowly overruns people and transforms them into statues, Sai, a twelve years old little boy, has the power to cure this disease with his blood. Since he is a child, his older brother, Vlad, martyrs him and preys on his gift by hitting him. One day Vlad lends Sai to his thug friends, who profit to cure their wounds and hit him, letting Sai sink into unconsciousness. In his dream, Sai discovers that he also has inside him, deeply buried, stone.
