A knock on your door sets in motion the feeling of anxiety. Should you open? Who, or what, will you encounter if you do? The characters of this continuous-shot anthology film – a billionaire, a commercial pilot, a trainee police officer, and a young single mother – find themselves in critical situations, facing the unknown. To make the right choice they must look deep within themselves, and recognize the true source of their fears.

What will happen if, as a result of biological warfare, almost the entire male population dies out? Women will grieve (for a short time), and then they will unite and create a new better world - with eco-towns, renewable energy, opportunities to do whatever they want, even science and biohacking, even yoga and self-development. Reproduction now occurs by artificial insemination, and only girls are born in the new world. But not everyone likes such a world order. Some of the surviving men and women loyal to them go to live in abandoned cities, begin to steal electricity, enjoying freedom and traditional sex. The tranquility of the ideally arranged female world is threatened when teacher Rada from the eco-city "Two Hills" meets the young "primate" Hera outside it.

Natasha dreams of becoming an Olympic running champion. She confidently moves towards her goal. But an unplanned pregnancy puts a girl before a painful choice - a professional career or motherhood?
