Catherine is a no-nonsense police sergeant who heads up a team of officers in a rural Yorkshire valley. When a staged kidnapping spirals out of control turning into a brutal series of crimes, Catherine finds herself involved in something significantly bigger than her rank, but unknowingly close to home.

Successful doctor Artur Planck, his wife Clara and their two daughters are seeking shelter from the Nazis storming Poland. They find a safe house in the farm of Emilia, their local grocer who is all alone after her husband fought for his country and never returned. Amidst the horrors of the war that surrounds them, an impossible love triangle erupts as Emelia uncontrollably falls in love with Artur. Such a fragile arrangement is sustained by love - or is it just the will to survive? The answer to that question may not even be made known to those who make it out alive.
