2017 m. filmas „Paskutinis didvirys“ pasakojo paprasto maskviečio Ivano (aktorius Viktoras Choriniakas) nuotykius, patekus į stebuklingą kraštą, kuriame gyvena didvyriai bei raganos, o burtai yra ne stebuklas, o kasdienybė. Ten Ivanas sužinojo, kad ir pats turi didvyrių kraujo, sutiko niekuomet nematytą savo tėvą (patį Ilją Muromecą) ir įsimylėjo nuostabiąją Vasilisą (akt. Mila Sivackaja). Ši juosta pasakoja apie tolimesnius Ivano nuotykius. Naujuose savo namuose vaikinas jau apsiprato, bet jį vis labiau kankina Maskvos ilgesys. Ne paskutinėje vietoje ir neišvengiamai artėjanti šventė, kurios metu iš visų karalystės kampelių suvažiavę didvyriai demonstruos savo ištvermę, galią ir sugebėjimus. Ivano nerimas didėja sulig kiekviena diena, nes vaikinas, nors ir didvyrio sūnus, tų stebuklingų, didvyrio vertų galių galių savyje taip ir nesugebėjo pažadinti.

A beautiful and kind girl, daughter of Baba Yaga, finds a magical stone Alatyr while walking in a field. It transforms her heart into a stone and puts her under a queer curse. She is to be the evil Countess of Stones and live in a stone tower. If the greatest gem-cutter in the world brings the stone of Alatyr to life, though, she'll become the ruler of the world. The Stone Countess, now cruel and selfish, is fascinated with the idea. She starts searching for the best gem-cutters and forces them to work with Alatyr, so the magical stone would become a living thing. Neither of the gem-cutters succeeds, so she kills them. While being imprisoned in her tower, they work on a large book about the secrets of gem-cutting. Each of them edits the book, so it's later named "the Book of Masters".
