Toshiro Mifune, trapped in a loveless marriage and bored with his position within his clan, would just like to enjoy his grandchild and see his sons have a happier life than he. But the same forces that conspired to trap him in his situation--duty to family and obligations to the clan and feudal chain of command--now threaten his son, daughter-in-law and granddaugher. Under great pressure, he resists the persuasion of his wife's family and his clan to bow to "duty". The tension builds--perhaps at one point a little too drawn out-- to an exciting climax.
