Caligula Alavacomgetepus, prefect of the Gauls, wants to make a strong impression in Rome and decides to offer Caesar nothing less than an Indomitable Gaul! Often isolated in the forest to exercise his talents, which his comrades taste moderately, the Bard Assurancetourix makes an ideal prey. Caesar, considering the rather deafening offering, gives the order to throw the bard to the lions during the next games of the circus. Asterix and Obelix leave for Rome to deliver their friend. And if all the paths lead to Rome, good news: with Asterix gladiator, the laughs are guaranteed!
