The aptly titled In Darkness is based on a true story from the Holocaust in Lvov, Poland, where a group of Jews escaped from the Nazi massacres by hiding in the sewers under the city. The film tells the story of that escape, but spends most of its running time on the subsequent rigours and pressures of survival in horrendous conditions.

The darkness of the title is three-fold. Firstly there is the obvious darkness of the events unfolding above ground, knowing those they knew and loved are being slaughtered metres above their heads. Secondly the physical darkness in which they find themselves, which must have been a daunting prospect to film. The set design and cinematography are to be applauded in this regard, as the sewers are brought to life with disgusting believability.

The final aspect of darkness explored comes from a strange place - the darkness forced into the hearts of good people faced with horrific events. This is not a simple film about heroic Jews overcoming evil Nazis - our protagonists are forced by circumstance into moral dead-ends and constantly struggle to keep the darkness out. Trying to cling to hope, respect and dignity has never been more difficult than when you are In Darkness.
