After their morning walk, Asterix and Obelix decide to go see Getafix. No sooner have they begun to discuss with the druid than Pneumatix joins them completely distraught. The village postman has just been attacked by a Roman detachment who wanted his bag. Intrigued by this rather curious theft, our two heroes decide to “nicely” ask their neighbors to return the village mail. However, our heroes will quickly discover that this theft, a priori, harmless hides something much more serious. A rescue mission then begins for our two brave Gauls.
