In Darkness 2011

Nazi-occupied Lvov, Poland, 1943: the weak prey upon the weaker, the poor steal from the less poor.

Leopold Soha, a sewer worker and petty thief, struggles to make ends meet for his wife and daughter. His friend, Bortnik, a high-living Ukrainian Police Officer, dangles the promise of a better life: all Soha has to do is find Jews hiding in the sewers. After all, no one knows the system better than Soha, who uses it as a hiding place for his loot.

Soon enough, Soha comes across a motley group of Jews trying to escape the upcoming liquidation of the ghetto by hiding in the sewers. They offer Soha money to protect them. Although he is aware that helping a Jew could mean immediate execution for him and his family, Soha sees this as easy cash and they strike a deal.
