A fire destroyed the Shen family's century-old foundation. Shen Yunjin climbed out of the pile of dead people holding half of the embroidery piece his father had given him. She hid in the bottom of the cargo ship, stabbed a strange man's shoulder with an embroidery needle, and fled to Shanghai. She started out as a wiring girl in a textile factory, feeling her swollen belly amidst the roar of the loom - the child's father was an enemy, and she wanted to use this "living evidence" to weave a web of revenge. Gu Beichen recognized her, but couldn't tell because his own family was one of the murderers. When the war breaks out and her siblings stand on both sides of the enemy and us, she discovers: What is more difficult than revenge is to trust someone again in the ruins.
