It’s the year 50 BC. The Empress of China has just been imprisoned following a coup d’état incited by Deng Tsin Qin, a traitorous prince. Helped by Finalthesis, the Phoenician merchant, and her faithful bodyguard Mai Wei, the Empress’ only daughter Princess Sass-Yi flees to Gaul to ask for help from two valiant warriors Asterix and Obelix, who are endowed with superhuman strength thanks to their magic potion. Our two inseparable heroes gladly accept to help the Princess save her mother and free her country. And thus begins a great voyage and adventure on the road to China. But Caesar and his powerful army, thirsty for a new conquest, are also heading toward the Middle Kingdom.
At Christine's funeral, her foster son suddenly shows up, a grown-up man with whom the family has been out of contact for quite some time. He brought a letter, stating that Christine wants to be buried in Wentelen, to the bewilderment of her biological children, and even more so to that of her husband. In addition to that, all the relatives are surprised that the foster son of Christine apparently maintained a correspondence with Christine. Nevertheless, Christine's last wish is respected, and they decided to bury her in Wentelen, and wish to do so traditionally, meaning walking behind the hearse. During a walk of several days, all the relatives (foster sisters, foster father, alleged friends and real ones, the foster son, lovers) have enough time to get to know each other better. Because in the end they have no other conclusion than that nobody really knew anyone. Old intrigues are dug up, the foster sisters finally learn why the foster brother just disappeared from the family, and they can begin to develop a real image of the mother. Once Christine's final resting place is reached and she is buried, all family ties, good and bad, are shaken around.
