In 2015, there was a story about an American department store investing in a Chinese beauty website. Lin Dan, who graduated from a prestigious American school, has already become a senior executive of the department store before she was 30 years old. She has a boyfriend named Daniel, who is a financial genius, and a colleague and friend Guo Pinfan who is the assistant to the first president of the company. She is considered to be the winning team in life, but she fell into the trough of being banned from the industry because she discovered problems with this investment case. After several struggles, Lin Dan had no choice but to return to China and work for a large Internet company. Although the environment has changed, the complexity of the domestic workplace is beyond Lin Dan's imagination. Coupled with missing her boyfriend, Lin Dan begins to doubt his original decision. Justin, a key figure involved in the investment case, also came to China, eager to find new goals to recover losses. His appearance opened Lin Dan's mind to rethink the investment project. Is he immersed in a new life? Or boldly pursue the conspiracy behind it? Can Lin Dan usher in the dawn of breaking through the dark night?
