The Fort of Death.

The second Bounty Hunter film, when master killer Shikoro Ichibei takes up the cause of a group of farmers being driven to despair by the vile Lord Ozeki. The villainous lord has driven them to mounting their last stand at a deserted fort against an army of attackers. Wakayama Tomisaburo is superb as an expert in killing and military tactics, who leaves his medical practice at a clinic for the poor in order to counter the vicious tactics of that vile lord.
