This is the story an amusement park employee named Jamal Walker who is magically transported back to medieval times in 14th-century England. There, Jamal meets Sir Knolte, a dissolute knight, before he stumbles into the court of the usurper King Leo. Jamal is impressed by what he thinks is the realism of the theme park; only after witnessing a gory beheading does he realize, with horror, where he really is. Jamal encounters the beautiful Victoria who is scheming to return the queen to the throne, and falls afoul of the evil Sir Percival. Joining forces with Sir Knolte and Victoria, Jamal teaches the rebels some helpful football, golfing, and boxing moves, before he dons the armor of the awesome "Black Knight"!

Tirante the knight is as committed to fighting the Turks in Constantinople as he is to relieving Carmesina, the heiress to the Byzantine Empire, of her virginity.
