After serving 2 years in prison, ISHIGAMI Takeshi (YAMAMOTO Yikken) spent two years working on a construction site and building up his funds before he returned to Tokyo with the help of Yasu, his best friend. He is determined to try and go straight but before he can do that, he has to raise even more money to break free of the criminal underworld and that requires a deep dive. He enlists his Korean friend Junghi and starts a business selling data for phone fraud to his Yakuza friend Yuki. As the business grows, Takeshi can just about make escape velocity, however, his old ties are holding him back and as a split in a yakuza family signals that start of a war, Takeshi finds himself getting dragged back down to the criminal underworld.

Shimada, a former Self-Defense Force member, suffers from severe PTSD following the loss of a comrade in a firefight in war-torn South Sudan, a tragedy covered up by the government. Shining a light into Shimada's solitary life in illegal arms manufacturing is a job as an apprentice at a traditional Japanese fireworks factory. There he begins crafting fireworks alongside the master artisan and fellow craftsmen who embrace fireworks that illuminate people's peaceful lives. Yet, parallel to Shimada's journey, his comrades-in-arms with unresolved feelings team up on radical acts to expose the government's cover-up, escalating tensions and pulling Shimada back into the darkness he thought he'd left behind.
