"Dangerous Woman" is the first female emotional suspense drama in China. It tells the story of four women joining forces for revenge, self-redemption in desperate situations, and a confusing "set-up" story. Lu Zicong asked lawyer Wang Chen for help. He suspected that his wife Qiao Wei wanted to "kill" him. At the class reunion three months ago, Qiao Wei ran into her ex-boyfriend Qi Kai and stayed drunk at Nicole's house all night. Su Yao, a college classmate who had a grudge with Qiao Wei, wrote an article on the official account "Where is the school beauty tonight?" From then on, the false veil of Qiao Wei's "perfect marriage" was unveiled, and the paranoid Lu Zicong frequently abused her. At the same time, Nicole's best friend He Anxin discovered that the scumbag who had sexually assaulted her had reappeared. Qiao Wei, Su Yao, Nicole, and He Anxin came together by chance. It turned out that the fate of the four women had been intertwined many years ago. They joined forces to fight back to help Qiao Wei get rid of Lu Zicong's control. A bizarre "car accident" and an article on a public account that revealed "murderous intentions" made Lu Zicong accidentally witness "their secrets". Wang Chen, the lawyer who had been assisting Lu Zicong in the investigation, suddenly "mysteriously disappeared."
