Max, Gerta, and their parents have abandoned their home and relocated to a safehouse in a different Berlin neighborhood. The Hoffmanns share the tight quarters with the daughter of a captured Becker Circle conspirator -- Kat Vogel, who is Gerta's age. Though they have strict orders to stay inside unless absolutely necessary, the three kids sneak out regularly, all while concocting a plan to keep the spirit of their resistance alive. They're going to burn down the headquarters of the Hitler Youth.
Meanwhile, Claus Von Stauffenberg, a member of Operation Valkyrie's inner circle, vows to carry out the assassination of Adolf Hitler himself. And he will do it soon. Time is running out.
The plots are carried out -- and a small, split-second decision changes the trajectory of history forever.
