The rivalry between Imperious and Koragg heats up, when the Knight Wolf's latest attempt to destroy the Rangers is intruded by the evil wizard. To settle the score, and decide if Koragg is worthy enough to regain his Dark Magic, Imperious places Koragg on trial for treason! Will his repeated failures, all in the name of honor, work against him in the eyes of the Master? Meanwhile, the Rangers work together on painting a mural for Rock Porium (if they can stop playing in the paint first) and Xander has a cold. (thetvdb.com)
