On a snowy night in the wilderness, with the military flag hanging down, Gu Linshuang went to die with a single gun, her blood-stained uniform still not taking a step back. She was the "lone star" that no one in the army dared to mention, but she was cut off by one person - Li Zhaoyan, the commander who personally sent her into despair. After five years of separation, the war reignited. He led his remaining troops to step on the corpses, just to find the woman who had blocked his fatal shot in the mountains of corpses and sea of blood. She hated him, but when the gunfire went out, she gave him her last breath. This is not redemption, but loyalty to death together - she swears by her life, and he swears by his life as redemption.
