Modern-day bikers make and break alliances with neighboring gangs, fight over the right to use a local petrol station, and are eventually united under a powerful leader. It's a replay of the events of Japan's 16th-century civil war, but with bikes instead of horses and knives instead of swords. Based on the manga by Jiro Ueno in Weekly Playboy.
Unfortunately the movie Bousou Sengokushi is not yet available on HBO Max.
