The story takes place in a fantasy medieval setting and starts with a young thief named Phillippe the Mouse escaping from an inescapable prison through its sewers. Said prison and the lands around it are controlled by a Corrupt Church led by a Bishop who is none too pleased to hear of Phillipe's escape, since the prison is supposed to be inescapable, after all. The Bishop sends his soldiers out to kill Phillipe, but just as they catch up with him Phillippe is rescued by the mysterious Navarre, who is accompanied everywhere by his Cool Horse and hawk.
