预言有外国侵略的日莲起誓,我今日起要成为日本的柱引要成为日本的眼目,而举起南无妙法莲莱经的旗在街道说法得罪幕府被判死刑,在刑场要行刑时雷声大响处刑中止,蒙古军来袭时不顾本身的危险立祈祷所、祈祷敌人降伏...Legendary Buddhist monk Nichiren (Kazuo Hasegawa) returns from his studies to lead Japan out of moral crisis and prepare to fight the Mongol invaders during the 1200's by creating a new form of Buddhism. He runs afoul of the existing Buddhist sects and their government supporters and is persecuted. Can Nichiren persevere before the Mongol fleet reaches Japanese shores?
