16-year-old Zhenya, whom everyone calls Zhest, fully justifies her nickname: she makes gestures and destroys relationships with everyone.
She became so after a concussion and a leg injury. now she limps and sees the world far from rosy. Zhenya blames her best (and now former) friend Prikhodko and directs all her anger and cynicism at him. But with the others everything is fine: parents, older brother, girlfriends and classmates. Everything changed after meeting the leader of the robotics circle, Stanislav, who becomes Zhenya's mentor. By interacting with robots, she learns to communicate with people, starts to enjoy life again and, above all, finds an old friend.
