Shimako Kanzaki (Alisa Mizuki) is an "OL" (female office worker) who has worked at the General Affairs department of a trading company for all of her 9 years with the company, and is called "Ms. General Affairs" by her co-workers. She is efficient, has a strong sense of responsibility and hates to lose.
Her company, to cut costs, decides to outsource some of their operations, including the operations of the General Affairs department, to a foreign company with lower labour costs. Shimako and her co-workers worry that their jobs are on the line, and are hostile towards the three Chinese trainees who have come to Japan (Tnag Jia Si, Rola Chen and Hu Bing) to learn the operations as a part of the company's outsourcing plan, as well as to their manager (Sadawo Abe). Shimako is assigned teacher to the trainees, and continues to object to them, as she thinks that she and her co-workers' jobs will be taken away. However, throughout the training period, both Shimako and the trainees become to understand more about each others' countries, and after going through a difficult situation together, Shimako begins to wonder if these people who she thought were her "enemies", were really her enemies or not.
