In medieval Europe, Phillipe Gaston, a thief known as “The Mouse”, escapes from the Bishop of L'Aquila’s dungeons right before execution. He is recaptured at an inn by the Bishop’s guards, led by Captain Marquet. However, the former captain, Etienne Navarre, shows up and defeats Marquet and the guards. He rides off with Phillipe while his hawk scatters other guards along the way.
