USSR, 1937. In a dark prison cell, a man burns piles of letters from innocent prisoners.
These desperate messages—scrawled on scraps of paper, tobacco wrappers, or written in blood—are meant to be destroyed without a trace. Yet, against all odds, one letter survives: a plea for help sent to the local prosecutor's office. A young, principled prosecutor receives the letter and decides to investigate. Convinced of the prisoner's innocence, he begins a determined effort to challenge the local NKVD secret police. His search for justice leads him to Moscow, where he seeks the support of the Prosecutor General of the Soviet Union.
Based on the novel by Georgy Demidov, Two Prosecutors follows the struggle of a man challenging a system of mass extermination, as he risks everything to seek justice during Stalin's Great Purge.
