Su Qingyuan, the daughter of a wealthy family who was abandoned by her family on the grounds of "heart disease", was picked up by Lu Yanshen, a mechanical genius who had just been released from prison, by the glacier in the twelfth lunar month and brought back to the leaky old home. One is Jinzhiyuye, who is too dirty to even light a fire, and the other is a severely sentenced prisoner who has been wrongfully convicted, but they form a bond of mutual redemption in a muddy town - she teaches him to trust the world again, and he leads her to split the thorns of survival.
When the Su family's motorcade came back from the dust, the teacher's diary hidden in the old pen, the blood-stained crescent jade pendant, and the pearl buttons on the grandmother's cuff gradually pieced together a conspiracy spanning fifteen years: her "illness" was a scam, his "crime" was a scapegoat, and the encounter between the two was written on the gears of fate from the beginning.
From the frozen soil town to the gilded cage, from the wrench of agricultural machinery to the business negotiation table, they fought against the fangs of capital with their dust on their bodies, and finally understood under the moonlight: the real salvation is never the thorns entangled with each other, but the light that shines together in the eyes when looking side by side at the fireworks of the world.
