A documentary film about Archpriest Nikolai Ryzhkov, a famous missionary in the Czech land in the early 1920s, before his arrest by the Austrians on August 7, 1914. He was imprisoned until July 1917; on May 7, 1917, he was convicted and sentenced to death. After an interstate exchange for the Uniate Metropolitan Andrey (Sheptytsky) in July 1917, he crossed over to Petrograd. During the revolutionary years, typhus, Spanish flu and other diseases raged in the city. Father Nikolai went from house to house performing services and rites. He did not refuse anyone, which greatly risked contracting himself. In February 1920, he became infected after performing a priesthood at home and died. The film is timed to coincide with the 150th anniversary of his birth and the 100th anniversary of his departure to the Lord. Numerous archival documents from the funds of the Slavic Library in Prague, archival records of the daughter and other historical sources were used.
