The Legend of Prince Valiant - Season 2 Episode 6
The Color of Honor

Believing that Sir Valiant has an innate understanding of justice, King Arthur appoints him to the distinguished post of Sheriff of Hammerscape. An honored Valiant takes Arn and Rowanne with him to the town to begin his duties. Its not long, though, before he learns how difficult it is to uphold both the letter of the law and the cause of justice. This dilemma comes to a head when Sir Bryant is accused of high treason by the towns mayor.
