On the day Wen Jianchuan buried his brother Lu Jiming in the ground with his own hands, his father knelt in front of the grave and called "son", his voice breaking like a knife scraping bones. Wen Jianchuan didn't cry, he just stuffed the blood-stained work badge into his trouser pocket - it was the only thing Lu Jiming held in his arms before he died. In the past ten years, Wen Jianchuan has transformed from a military engineer to an underground arms broker, just to find out the cause of his brother's death; and among Lu Jiming's belongings, there is a torn military secret order, signed by Wen Jianchuan's own code name. The truth about the fratricide was buried in the abyss of blood and code, and now, he had to tear open that layer of skin with his own hands and let the living people kneel and confess their sins.
