The protagonist Otto Meier is a young engineer. In 1916, he joined the Bavarian Aircraft Manufacturing Company (BFW) with the dream of manufacturing the most advanced aircraft engine. With the end of World War I, the Treaty of Versailles prohibited Germany from manufacturing aircraft, and BFW faced a bankruptcy crisis. Otto and his like-minded colleagues were unwilling to fail and advocated the transformation of the company. They applied aircraft engine technology to motorcycle engines and developed the BMW R-32 motorcycle, which ushered in BMW's land two-wheel era. Later, they keenly grasped the potential of the automobile market and entered the automobile manufacturing industry by acquiring the Eisenach automobile factory. In this process, Otto not only had to deal with technical problems, but also had to deal with the board of directors, investors and competitors. Every technological breakthrough and every business negotiation was a thrilling contest. When BMW cars gradually emerged in the market, World War II broke out and the factory was bombed. Otto and his team struggled to restart amidst the ruins, eventually creating BMW's glory today.
