Jojo is a keen Hitler Youth member in World War 2 until he comes across a teenage Jewish girl who is being hidden in their attic by his mother. While dealing with his imaginary friend, an alternative Adolf Hitler, he starts to question his beliefs.

Quirky comedy by Taika Waititi, who also stars as Adolf Hitler, underlining the seriousness of the situation for Jews during the war whilst largely treating the German characters as comical. Roman Griffin Davis is the innocent Jojo.
