The sad brothers Edward and Alphonse tried to use the biggest taboo in alchemy - human alchemy to save their mother who had passed away, but they encountered a huge disaster. Alphonse, who lost his body, had his soul sealed in the armor, and Edward forced his brother to stop at the gate of the underworld at the cost of his right arm and left foot. Many years later, Edward (played by Ryosuke Yamada) grew up to be the youngest fullmetal alchemist in the country. He and his brother (voiced by Mizuishi Ahimu) worked together to find the philosopher's stone. At the same time, the mysterious artificial people Rast (played by Yasuko Matsuyuki) and Envy (played by Kanata Hongo) lingered in the corners of the country. They planned terrifying activities, and the sky was overcast for a while... This film is adapted from the original manga by Hiromu Arakawa.
