Following an argument and a stupid bet between Abraracourcix and his brother-in-law, Asterix and Obelix went to Rome: their mission was to bring back the crown of Caesar's laurels so that it could perfume the stew that Abraracourcix had to offer to his brother-in-law. The part would not be easy, for it was out of the question to enter Caesar's palace by force. Our Gauls must therefore find a way to enter it discreetly to bring back the crown, a crown that put a bad will to be found.
