Movie's information

The Synopsis:

When the full-scale invasion begins, Kira can't get away from her internal fever - she has to go to the frontline. She is 28 and she is a veterinarian, so it is just natural for her to become a paramedic. But there is one "but" - her twelve-year-old son, Vitia, whom Kira is raising alone. So the first question is: with whom to leave the child? The second question is whether Kira can really leave her son? She has been a mother most of her life. She has always protected her son herself, always been there for him. Maybe it's time to protect something else?
