July 1945, Far East. The Soviet Red Army is about to launch a general offensive, but the Kwantung Army has a hidden trump card - a female special agent team code-named "Red Sakura". All members are elite. Commander Ono Yoshiko has killed more than 40 anti-alliance people by herself.
The Soviet army formed a five-member task force to go deep behind enemy lines: a captain who was an orphan from a massacre, a sniper who locked throats thousands of meters away, an Oroqen girl who played with booby traps in the mountains and forests, a four-language genius who deciphered codes, and a medical soldier who rescued people under the gun line.
Mission: Pass through three blockades and bomb the Jiamusi communication hub.
But Hongying has set up a skynet, and the inner ghost "Red Fox" is pushing them to a dead end.
In the birch forest, five women versus five women, every shot is a blood debt.
