TV reporter Wei Haiyi (Played by Maggie Shao) interviews the cage house where the urban poor live, and meets the young Ma Zhongbao (Wen Zhaolun). Zhongbao grew up in a cage house since childhood, indulged in reading all day long, and his personality was extremely closed. After the interview, Haiyi inadvertently took away Zhongbao's novel "Frog and Scorpion", and was deeply impressed by Zhongbao's bitter pursuit. The highly reputable lawyer and lawmaker Cham Yourong (Luo Yingjun) is the underground lover of Haiyi's mother, Wei Jinling (Miao Jinfeng), but intends to invade Haiyi, and Haiyi kills him in a hurry. The mercenary Jin Ling accepted a huge bribe from Rong's wife and even testified against her daughter in court.
