Coming of age, a girl is told the truth about her dead father: he is alive, but imprisoned for several crimes he did not commit... With the help of an old noble lady and a young count (who doubles as a daring sea captain), she will fight for the truth, and justice. Her opponent is the State Town's Inquisitor himself, who set her father's up to escape his own crimes.
