Set in the Japanese puppet state of Manchukuo, the film follows four Chinese Communist Party agents who parachute back to Harbin in Northeastern China in the early 1930s. Together, they embark on a secret operation code-named “Utrennya” (Russian: "утрення") that intends to extract a former prisoner who could expose the unethical human experimentation and other crimes against humanity committed by Unit 731 of the Imperial Japanese Army in front of the international community. Upon landing, the team members split into two groups to avoid being captured and tortured to sell out their loved ones on the other group. They are also ready to sacrifice by ingesting cyanide-equivalent pills contained in a match box. Soon after their separation, group 1 discover their local contacts are disguised by enemies. They manage to escape the trap, but also realize they had been sold out by a traitor, who cave after being tortured and witnessing the execution of his fellow comrades. Will group 1 be able to inform group 2 and carry out the mission? That is the question on the snowy grounds of Manchukuo.
