On the cusp of World War II, Lena Papadopoulos yearns to leave circus life behind, disappointing her father, the extraordinary headlining illusionist, Theo. Brilliant and curious, Lena—who uses a wheelchair after a childhood bout with polio—yearns for the real-world magic of science. During the war, Lena's father and her friend Alexandre are arrested and made to perform in a town for Jews set up by the Nazis. Forced to make her own way, Lena must dare to believe in the impossible—herself.
