Based on the same-titled novel by Ikeido Jun (the writer of Hanzawa Naoki series), the drama unfolds against a backdrop of economic recession. Hosokawa Mitsuru is the current president of the core-precision tools manufacturing company, Aoshima. He was personally recruited from another company by the company's founder, Aoshima Takeshi. Needless to say, this move was not well-favored by the existing management who themselves were vying for the job. Not long after Mitsuru joined the company, the global financial crisis caused the economy to slump, and Aoshima was certainly not exempted from the ill-effects of the slump, which was accentuated by fierce competition within the industry.
