On the day of the college entrance examination, Zhao Jianguo, relying on his wealth and power, used wedding cars to block Lin Xiao's road and mocked that poor people do not deserve to change their destiny. At the construction site, he deducted food expenses, delayed wages, forced injured people to sign unequal agreements, and even sent people to threaten Lin Xiao and his mother. From a poor student trampled underfoot, Lin Xiao becomes a counter-attacker who masters evidence and uses the law as a sword, step by step uncovering the crimes of the Zhao family, ruining the villains and making them pay the price, and seeking justice for himself and all bullied people.
