In a dilapidated, cold and leaky warehouse, young painter Lin Wei is in deep trouble with her unfinished work "Cocoon Room". The seventh attempt to destroy the painting not only left a dazzling cobalt blue stain, but also caused the reflection of the knife-wielding doctor in the pupils of the canvas - Dr. Liu, the blind date that my mother insisted on arranging.
And the appearance of Chen Yuan, a man with a scar on his collarbone and a strong turpentine smell, all hinted at a deeper whirlpool. Lin Wei struggles on the edge of the cracks between artistic pursuits, family constraints and self-understanding. This "unfinished rain" not only wets the canvas, but also washes away her shaky sanity and future. Can she find a way out of the cocoon or complete her transformation before the rain stops? Everything is up in the air.
