When William Gridley arrives from the US in London, he rents part of Carly Hardwicke's house from her and promptly begins to fall in love. Gridley doesn't know that many people think she killed her husband but his boss, the American ambassador, knows and doesn't take this lapse of judgement lightly. Since Carly is also American, Gridley saves his job by introducing her to the ambassador, who is promptly smitten and promises to help her. So when a Scotland Yard detective arrives, wanting to get to the truth one way or another, they say they'll help him. And then the comedic complications really begin.
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.
