Blind painter Su Yan grabbed a stranger's sleeve on a snowy night on New Year's Eve and made a self-destructive proposal: "Do you want to marry me? I'm very cheap - progressive eye disease, spinal cord injury, and a collapsing heart."
She didn't know that Xia Zhihan, a genius scientist in a neat suit before her, had long been the "chief observer" of her life: from the half-pipe of ultramarine left on the Left Bank in Paris to the blood-stained handkerchief backstage in Vienna; from every medical prescription to the thermal imaging of her late night sleep – her seven-year broken traces were meticulously collected, archived, and displayed by Xia Zhihan into a private museum.
This marriage is a sick contract. Su Yan surrendered her disabled body and loneliness in the dark in exchange for top medical resources and a barrier-free future. Xia Zhihan handed over his absolute desire for control and state-level resources in exchange for a "sample of humanized transformation." A painter who has gradually lost his world, an observer who has never learned to love normally, begins to build some kind of abnormal symbiosis between data and paint, monitoring and touch, cold agreement and hot obsession.
But the cracks already existed: Su Yan didn't know that the fate-changing explosion in Paris was no accident; Xia Zhihan didn't calculate that the cage he designed would eventually imprison the observers. When the possibility of regaining sight suddenly comes, and when the secrets of Xia Zhihan's childhood laboratory surface, they must answer - who is saving whom in this marriage that started in a snowy night bar? When the light really shines in, do your eyes that are used to darkness still dare to see clearly the most primitive and imperfect form of love?
