Truus Oversteegen, her younger sister Freddie, and their friend Hannie Schaft, were just teenagers when the commander of The Dutch Royal Army surrendered to the Nazis. As the German-controlled government slowly began to pen in the entire Jewish community and force them indoors, so the girls were compelled to become involved in The Resistance.

Intelligence-gathering. Spying. Sabotage. Murder.
