Bottom-layer manual laborer Chen Jianguo, due to being long humiliated and bullied by black-hearted restaurant boss Wang Deli, with nowhere left to forbear, exhausts his family wealth to open a budget small eatery. Facing Wang Deli's malicious competition, spreading rumors and smearing, and the harassment of the bought-off street administrator, Chen Jianguo tenaciously fights back relying on honest management, coworker support, and legal weapons. He not only successfully exposes the opponent's illegal act of using expired ingredients, but also reports the administrator's corruption, ultimately making the black shop close down and the wicked punished, while his own small shop wins praise and dignity.
