«The Return of the Prodigal Son» is the first volume from the film (novel) of Anatoli Vassiliev’s «Empire» inside the Dau cycle. The story is about inner kinship, which is much closer than blood, about inevitable betrayal, about almost fatherly love and forgiveness. Cigarettes (papirossa), images from «Faust» and «Don Juan», walks in the Soviet Park of culture... And a terrible, narrow gap inside the brutal regime where you have to be skilled enough to survive... Yes! and they also play gorodki (skittles) with childish passion!

Nikita Nekrasov is a scientist, a theoretical physicist who studies our world and other possible worlds. He refuses to make a choice between mathematics and physics, between one woman and another, as he ponders the existence of the multi-universe. At scientific conferences, attended by eminent foreign scientists and a rising younger generation of physicists alike, Nekrasov gets carried away debating the beauty of string theory. He attempts to explain to all of his women – Katya, the librarian, Zoya, the scientific secretary, Svetalana, the head of department – about the theory of his own polygamy, and the possibility of having enough feelings to satisfy everyone.
