At nineteen, Zhou Haisheng leaves his hometown with the two hundred yuan his father gave him, hoping to earn a little more through his own efforts. From assembly lines and construction sites to an internet company, he discovers income far beyond an ordinary salary for the first time. Yet with every choice he makes, he gradually strays from his original path. Later, he joins Xu Man and He Mingyuan in starting a business with just three computers. Their enterprise expands rapidly, while wealth and desire spiral out of control. Only when an extensive investigation network quietly closes in does he realize that there is no such thing as a truly guaranteed profit. Through Zhou Haisheng's experiences, this drama warns viewers that when tempted by high returns, they must hold fast to their principles, make rational judgments, and stay away from illegal schemes.
