The Lord of Night wants to have gaol-break of the prisoners in Denmachō prison so they will commit crimes and disturb the peace of Edo in order to bring about Sadanobu's downfall. Kongō undertakes to get himself arrested by disguising himself as a rōnin and killing and robbing a series of people. Once in the gaol he overpowers a guard, steals the keys and is about to release the other prisoners but is foiled by Shintarō who had recognised his sword style.
