A successful executive from Yokohama (who is secretly a ninja) decides to move to America to open a restaurant in a slum for some reason. He runs afoul of the local gangsters on the first day, and ends up having to kill every single one of them. Weak story, bad acting, and terrible music, but Sho Kosugi has a few decent fight scenes where he takes out multiple attackers. That ninja helmet is pretty awesome, too.
