Michael and Dima, or Dima and Michael are childhood friends. They grew up together, share a business together, live next door to each other, even their children play together. They are the very best of friends and have a truly unbreakable bond… or do they? On the eve of their children’s wedding a dark secret emerges, shattering their friendship and turning best friends into lifelong enemies.

The year is 2140. Society has undergone profound change and is now run as a matriarchy, thus removing its reliance on men. Two Hills is one of the communities founded by this new order. It is a place of perfection, where there is harmony rather than conflict, science and reason prevail and the environment is protected and respected. One of its inhabitants is the history teacher, Rada. On her birthday she takes her students on a guided tour of a special area outside of Two Hills, a place where the so-called “primates” live. The "primates" are men (and a handful of women) who have chosen to live beyond female control. However, the tranquillity of Rada’s perfectly arranged female-centric world comes under threat when she meets the young "primate", Hera. It’s a classic girl-meets-boy story, in a world where the rules have fundamentally changed.

Psychologist Nastya Gracheva is a girl of strict rules from a decent family. She becomes disillusioned with men after the betrayal of the groom and decides on an unusual experiment. Nastya promises her colleagues to get married in the near future, but necessarily for love and with the help of the scientific method. Testing of the staff of her native institute points her to a suitable candidate — zoopsychologist Tema Maslov. The heroine suggests that he test her theory in practice: subjugate the heart to reason, fall in love with each other for the sake of science and deduce the formula of love in order to rid humanity of love suffering forever.
