Ye Tian, a craftsman of ancient hemp coir raincoat, reunites with his first love Lin Xiaoman who left without saying goodbye seven years ago during the rainy season. She returned to the mountain village with a research mission on intangible cultural heritage, and he was as silent as ever, guarding his needlework under the eaves. The stitched seams of a coir raincoat hide the entire history of the two of them being torn apart by reality since they first encountered the rain. If the stitching is too dense, the fabric will burst, and if the stitching is too sparse, it cannot block the slanting wind and drizzle. Just like when he had sewn all the escape routes, she chose to walk away. She will leave again in seven days. This time, can he use dense and dense threads to sew the cracks eroded by time and sun? The hemp threads swollen by the rainy season and the eaves that have become brittle in the sun are questioning: Can the unfinished words of those years be kneaded together like a broken hemp rope? In the rough texture of the mountains, rain and thimbles pierced the silence at the same time, forcing the two people to face the old scar that had never healed.
