A self-proclaimed "knight" and his hapless squire travel the Spanish countryside, attacking "giants" that are really windmills in his attempt to win the love of the fair Dulcinea.

The poor landowner Don Quixote is obsessed with chivalric romances. One day he gets the idea that he must restore the order of the wandering knights and even ride out on horseback in full gear. He persuades a simple peasant Sancho Panza to act as a weapon bearer with a promise of royal rewards. Although this at first seems to be a long way off, the hard-working pair suddenly set about a task that can turn them into real knights.
