In the Twelfth Century, the Count Thibault Malefète travels with his family from France to England to marry his beloved Princess Rosalind, the daughter of the King of England. His rival and enemy Earl of Warwick hires a witch to prepare a magic potion to Rosalind to give up marrying Thibault. During the wedding feast, Thibault drinks Rosalind's wine spiked with the potion and has hallucinations. He kills Rosalind believing she is a monster and is arrested in the castle. Thibault asks his servant, André Le Paté, to bring a wizard to send him back in time before killing his bride. However, the wizard forgets an ingredient in the potion and sends Thibault and André to the future, to the Twenty-First Century. They arrive at a museum in Chicago and creates a havoc, being arrested by the police. But the museum employee Julia Malefète believes he is her French cousin, who drowned while yachting three years ago and the body has never appeared, and now is amnesic, but Thibault notes that Julia is his descendant. She brings them to the house of her gold-digger fiance Hunter, who has a lover, Amber, and is only interested in her money and real estates. André falls in love with the next-door gardener Angelique, who explains him the modern labor laws. Meanwhile, the wizard decides to follow Thibault and help him to return to the Twelfth Century.
