In the darkest place that devours light on the northern border of Myanmar, Gu Yunshen, a rational criminal psychologist, and Lu Lin, a wild and untamable anti-drug hero, are forced to form a partnership. In the first confrontation, the collision of ice and fire spewed out sharp hostility. He is a "stargazer" who is good at calculations and firmly believes in data and logic; he is a "night devil" who tears apart the night by instinct, trusting in fists and intuition.
From the bizarre "Cat Transformation" gambling game to the bloody "account book" mystery, from the "copycat" who manipulates people's hearts to the invisible hand that creates the "emotional plague"... The twelve progressive unit cases, like twelve keys, gradually open the way to the criminal core of the transnational criminal group. The two caught a glimpse of the flashes and scars of each other's souls in the game of life and death.
Living under the same roof, they develop a tacit understanding of warmth and warmth; when they go deep into the tiger's den, they become each other's only back and eyes. When the final shadow appears, they must cross the boundaries of nationality and identity and face the madness that can distort reality. This is the ultimate showdown between justice and greed, and it is also the only coordinate confirmed by the two lone stars in the endless darkness - from opposition, to symbiosis, to a desperate journey toward death.
Philosophy: On the darkest border, two top police officers, in a crime mystery intertwined with blood and fire, went from being incompatible with each other to supporting each other. They not only hunt down the shadow of transnational drug lords, but also complete the redemption and reshaping of each other and themselves in life and death games. The story explores how in absolute darkness, individuals use reason and blood as blades, and trust and bonds as shields. While protecting justice, they also find the integrity and light of human nature, explaining the importance of the word "walking together" more than life.
