With infectious Jew-hate-laden rhetoric from Nazi Germany spreading into Austria, it is only a matter of time before their bond of friendship gets severely tested.

In a world filled with danger, heartbreak, and impossible choices, the blood sisters must navigate through the darkness to find love, redemption, and a chance at survival.

In the early 1940s, countless Jewish families were imprisoned in the Warsaw Ghetto before being led to their deaths by the Nazis.

But Helen's heroism comes at a cost. Because harboring a Jewish person is a crime to the Nazis, with severe punishment - even death - as the penalty.
