小鬼当家2

　　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.
