After fleeing Europe for Uruguay during WWII, Jacob Kaplan built a quiet life. Now 76, he begins to question his worth. After learning of a mysterious German prowling the shores of a nearby beach, he becomes convinced that he's found a Nazi in hiding and plans to expose him. Expertly distilling a potent mixture of emotional depth and deadpan comedy, Mr. Kaplan is a vivacious meditation on family, aging, and the drive for significance.

While King Louis X of France is on a campaign, Queen Marguerite is reigning in Paris. During this time, the inhabitants of the city are disturbed by mysterious murders near a tower.

After her husband dies, a German woman who gave up her infant for adoption to emigrate to America returns to Germany, discovering that her child is being raised by a married orchestra conductor.
