The childhood of the young Orthodox priest Dmitry passed back in Soviet times, which was reflected in his upbringing and development, because he had to grow up between two fires. The most dear and close people were divided into believers and atheists. Having reached the age of majority, he decides to become a priest. On the path of life, he encounters anger, pity, mistrust and pain, but firmly believes in his ideals. This helps him to bring goodness and peace in his ministry and in worldly life, to help and give hope to desperate people. But one day, evil from the past overtakes Dmitry himself. What will happen when the priest himself faces the main question in his life?
Baseado em uma história verdadeira, o filme conta sobre o famoso lançador de foguetes russo apelidado de "Katyusha", que foi mantido em grande sigilo durante a Segunda Guerra Mundial.
