Jones is a widower when he meets the young Anna-Luise Fischer in a local restaurant. Jones is surprised to learn that Anna-Luise is the daughter of Dr. Fischer, who has become rich after inventing a perfumed toothpaste and whose dinner parties are famous (or infamous) around Geneva. After a brief courtship, the two are married.
