Operation Barbarossa enters its third day as the German army march into Kaunas, Lithuania. The majority of residents welcome them as liberators now that the Soviets have fled. Others, though, are not so sure. One man, Jonas Petraitis, Chief of Police in Kaunas, is up against it from the start. Major Ulrich Kruger from the Wehrmacht and Captain Hardy Steltzer from the Einsatzgruppen, the Reich's murder squad, take over his police station.
From there, the persecution of the Jews in Kaunas begins. A ghetto is established and preparations for Hitler's 'final solution' are underway. Atrocities are committed, but the inhabitants of the ghetto fight back from the outside. They form a resistance movement and crawl beneath the wire time and again to disrupt the German war machine only to return and plan another day. Max, Karlis and Kowalski local partisans whose expertise in fighting the might of the Soviet Red Army is invaluable aid them. But like the inhabitants of the ghetto, not all of the partisans survive.
Across The Green Border is an extraordinary, moving story of Jews incarcerated behind barbed-wire knowing that each day they survive is one day closer to their extermination.
