Our days. Seventeen-year-old schoolgirl Zhenya comes from the "northern capital" to a border village in the Belgorod region to see her brother, a volunteer, before he leaves for the SVO zone. There she meets a local informal leader, call sign "Timur", and his team, also teenage volunteers, who not only help Zhenya see her brother, a tanker, while helping the Russian "security forces" eliminate an enemy sabotage and reconnaissance group, but also completely change her outlook on life. And as it happens, the personal relationship between Zhenya and "Timur" goes beyond "just friendship".
