Wilfred of Ivanhoe (Anthony Andrews) is a young Saxon knight of 12th century England. Returning home from fighting in the Crusades, he finds that the nation is now under the dictatorial thumb of the king's brother, Prince John (Ronald Pickup) and the prince's thuggish Norman cohorts. He is also dismayed to learn that his longtime love, Lady Rowena (Lysette Anthony), has been betrothed to another man. Determined to restore throne and country to Richard, the courageous Ivanhoe has soon run afoul of those in power, though a few rebellious types like Robin Hood (David Robb) are on his side. Ivanhoe also finds love again, with the lovely Jewish girl Rebecca (Olivia Hussey), though she and her wise father Isaac of York (James Mason) face Norman persecution for their religious faith. Ivanhoe also finds a deadly rival in the cynically twisted knight Brian de Bois-Guilbert (Sam Neill).
