In a quiet coastal town, a missing bag of drugs ignites a chain of chaos, pulling together a detective, a desperate father, an ambitious young woman, and two siblings caught in addiction. As their lives collide, a risky rescue mission begins—one that no one will walk away from unchanged.

一个偏僻闭塞的沿海小镇，被一袋消失的毒品打破沉寂，一场“自杀式拯救”正式拉开序幕。一个是意外卷入毒品交易现场的女刑警胡文静，一个是为救女儿不计代价的普通父亲程恳，一个是一心想要逃离小镇生活的野心家李晓雅，一个是被毒品吞噬而走向异途的姐弟王萍王安。欲望与贪念交织成的茧细细密密困住了每一个人，无人能够全身而退。
