Nakayama Yasube (Ookochi Denjiro) is a ronin (an unemployed masterless samurai). He lives in a poor section of Edo (the present Tokyo). He spends his time drunk on saki that he buys with money he gets from settling fights. When he comes across a scuffle, he breaks it up, forces the two parties to make up, and demands payment for his services. His nicknames are Fighting Yasu and Carefree Yasu.
The date is July 21st, 1694. Yasube returns home drunk after having broken up a fight. There is a letter from his uncle who has been challenged by some bad samurai. He has gone to Takadanobaba, where he will do battle. He is greatly outnumbered. Yasube, immediately comes to his wits, grabs his sword and sets off in a dash. After covering the long distance at faster than marathon pace he finds that the battle has already begun. His sword is swift as he finishes off tens of the enemy. —Matsuda Film Productions
