This outrageous time-travel comedy follows the misadventures of a wacky medieval knight (Jean Reno) and his faithful servant when they are accidentally transported to contemporary times by a senile sorcerer. Mayhem rules as these 12th-century visitors try adapting to the wildly confusing modern world. To avoid being stuck here for good, however, they soon begin an all-out cosmic assault on their former castle -- now a luxury hotel -- in their quest to return to the past.

Sibylle, a young Parisian with long teeth, intends to shine in her new job by buying a hardware store in the Basque Country to set up a supermarket. She imagines that she has "rolled" the old owner but the latter is under curatorship. Sibylle must therefore deal with Ramon, the nephew, to recover his money and sign as soon as possible. Otherwise, the ejection seat is assured. She will soon realize that the Basques do not intend to let themselves be made by a Parisian, however pretty she is.
