Kilteegan Bridge, Ireland 1963. On the face of it, life is idyllic for Eli and Lena Kogan. Living in their beautiful house in the Irish countryside, their children are growing up happy and safe surrounded by a loving community. So when a letter arrives one day threatening to shatter their peaceful and prosperous world, Lena and Eli have no option but face the dark reality of their situation. How best to do that, is something that drives a wedge between them. As a Jewish child, escaped from Germany in 1939, Eli is all for letting those dark days where they belong, for him, there's no future in the past. But for Lena, it's different. She knows that the only way she can move her family forward in peace is to first go back, and there is only one man who knows the whole truth. From rural Ireland to wartime France, What Divides us, tells a tale of loyalty and love, resentment and revenge, that has far reaching consequences for the Kogan family, the unravelling of which might just destroy their future.
