Kaiser Wilhelm II of Germany abdicated his throne in 1918, retreating to the Netherlands, where he lived in exile for another couple of decades. Adapted from the Kaiser's Last Kiss, a novel by Alan Judd, The Exception looks at the Kaiser's life during the heyday of the Third Reich, which the Kaiser evidently hated for its boorishness. A brilliant Christopher Plummer plays the Kaiser as a character reminiscent of a Tolstoy creation, an intelligent but mildly deluded ruler who never has accepted his fall from power. The story kicks off when the Nazis assign a German captain (Jai Courtney) to watch over the Kaiser and keep an eye out for spies. Courtney's Capt. Brandt evidently has been banished himself; he's on a punishment assignment for having gotten crosswise with the SS during a stint in Poland. The Kaiser surrounds himself with a small coterie of loyalists that includes a military aide (Ben Daniels) and the empress, a fine Janet McTeer. The story of a rueful monarch in exile is muddied by Capt. Brandt's infatuation with one of the kaiser's servants (Lily James). Director David Levaux focuses much of the movie on the relationship between the captain and the servant girl, a young woman who happens to be Jewish. Questions about the meaning of loyalty arise for the smitten Capt. Brandt, but the movie's emphasis on romance costs it some hard-edged credibility. Eddie Marsan appears briefly as Heinrich Himmler.
