In City X in the 1980s, the wind was filled with rough energy. Yin Wenhao, a high school student with no background and power, formed the "Three Coward Group" with the chubby Hu Xiang and the skinny An Hao, and became the punching bag of the school bullies. He has a photographic memory, but he can only use it to remember tricks to bully others. Once, to protect Su Qing, he was beaten almost to death, which also awakened the ruthlessness in his bones. The three began to join forces to resist, and gradually formed their own small circle from stealing protection money from small traders. When they enter the society and work hard, they encounter betrayal. The brothers around them may be undercover police officers, and every step is like walking on thin ice. Su Qing's father was a gangster and suppressed him in every possible way, but Su Qing didn't know it and thought her father was an ordinary businessman. Yin Wenhao is surrounded by many women showing good intentions, but in his heart he only has Su Qing. Hu Xiang never dared to take action to become ruthless, while An Hao followed him from being a fool to having no plans left.
