Prince Valiant

After his father is overthrown as the Christian King of Scandia, his son Prince Valiant travels to the court of King Arthur at Camelot in hopes of being made a knight of the Round Table. On his way there, he has an encounter with a Black Knight, whose mysterious movements have stirred unease at Camelot. Before Valiant can become a knight, he must first serve as a squire, and Sir Gawain takes on the responsibility of training him in the skills of knightly combat. Valiant eventually meets the beautiful Aleta, daughter of the King of Ord; in introducing Gawain to his new love, Valiant gives Gawain the mistaken impression that Aleta is in love with him, and then does the honorable thing by refusing to disabuse the older knight of his romantic thoughts about her. Valiant and Aleta are taken prisoner by Vikings but manage to escape and assist in thwarting a plot by the Black Knight to overthrow King Arthur.
