Inspired by Jacques Martin, a striking evocation of one of the founding events of the history of Gaul. In 52 B.C., Gaul is in full boiling. The aim of the Gauls was to attract Caesar's legions to the fortress of Alésia and there, finally, to engage the decisive battle that will lead to the destruction of the enemy once and for all. In the Celtic imagination, Alésia, the "city of the Mandubians", is both a military lock and a sacred symbol: to inflict a decisive defeat on the Romans in such a place can only be a guarantee of a radiant future for the Gaulish cause, an attack on freedom. But unfortunately for Vercingétorix and his allies, Caesar's strategy of binding at the foot of the fortress will turn against them and the siege of Alésia's famous events will return to the character of a military party.
