Tsukuda Kohei was once a researcher with the Aerospace and Science Exploration Agency and now runs Tsukuda Industries, a small factory which was left by his father. Although his relationship with his teenage daughter Rina is somewhat strained, business at Tsukuda Industries has gradually started to improve. But Tsukuda puts too much effort into his dream of developing a rocket engine and business declines little by little. One day, a major client suddenly declares that it is dropping Tsukuda Industries. Then, Tsukuda Industries gets sued by a big rival company, Nakashima Industries, for patent infringement.

On October 14, 1947, Captain Chuck Yeager accomplished what many thought was impossible: he broke the sound barrier and in doing so, changed aviation history forever. Behind this remarkable achievement was a dedicated team of rocket scientists and engineers, and one incredible plane, a Bell X-1 named "Glamorous Glennis." This is the story of the plane and the people who dared to travel faster than the speed of sound, pushing flight science forward and proving that no matter the barrier, humanity can find a way to break through.
Kohei’s company holds the patent of an engine valve system required to develop a space rocket. Will he finally be part of a successful rocket launch?
