Jojo is a lonely German boy who discovers that his single mother is hiding a Jewish girl in their attic. Aided only by his imaginary friend -- Adolf Hitler -- Jojo must confront his blind nationalism as World War II continues to rage on.
1944 Germany. Ten year old Johannes Betzler, more commonly called Jojo, is the son of good Germans, his father away fighting in Italy, while he is under the care of his mother Rosie, with his older sister Inge recently having passed away from illness. With only one true friend in the form of same aged, bespectacled Yorki, Jojo, in wanting to fit in, is arguably entering what he would consider the most important phase of his young life in attending a Nazi youth camp presided over by Captain Klenzendorf, Captain K's almost too faithful assistant Freddy Finkel, and Fräulein Rahm, who takes Nazi policies in a slightly off-kilter direction. Despite being considered an outsider by most of the other youth in town, Jojo figures he has a leg up on everyone else at camp in that he is constantly being guided by the spirit of Der Führer himself, Adolf Hitler, whose personal bodyguard Jojo aspires to be when he grows up. In his general day-to-day life but also supported by his time at camp, Jojo has a hatred for Jewish people despite not really knowing anything about them or ever having met anyone of the Jewish faith, the ultimate goal to kill them. So when Jojo meets someone Jewish for the first time, especially as that meeting is in what is for him the most unlikely of circumstances, Jojo has to figure out what to do. While truly believing he is a Nazi despite not really knowing what that means, he has to decide either to follow what he has been taught in hating and trying to kill any Jewish person despite knowing that killing is not in his true nature, or not, which may have larger consequences with relation to family. While he decides, he truly gets to know the person beyond the label of "Jewish" which may factor into what happens.
