In the 1770's, the shrewdest man of the age, Tanuma Okitsugu, had abused his political power, and the corruption of government officials and moral decay of the public were prevalent. At that time, there was a box for complaints made by the general public. It was called "Meyasubako" and was placed at the front gate of the central government's Supreme Court. The appeals went directly to the shogun who assigned the “Otakagumi” (Falconers Unit) to investigate. Led by Uchiyama Kanbei (samurai superstar Mifune Toshiro) they fought injustice and helped the oppressed. Not only were they skilled swordsmen, but their trained falcons would swoop down on enemy troops, especially those using firearms. Superb fighting throughout with Mifune at the forefront in one of his finest roles.

As the vile Tanuma Okitsugu continues to abuse his political power, more and more clashes with the Falcons of Edo, who stand for justice and morality are bound to occur, leading to a conclusion the likes of which has never been seen. Putting his life on the line, time and time again, Uchiyama Kanbei fights to prevent Tanuma from destroying the falconers’ group and take him to task for his vicious treatment of the Japanese people. Aided by his trusty Vice-Chief Ichiyanagi Kakuto, he wades bravely into battle in a land where “Take no prisoners” is the mantra. Brilliant fighting and a clever story line create a highly charged action series that brings out the best in samurai cinema. Can the Falcons of Edo prevail and save Japan from being crushed underfoot!
