Run Boy Run (2013)

Run Boy Run is the true story of Jurek, an eight-year-old boy, who escapes from the Warsaw ghetto, then manages to survive in the woods and working as a farmhand, disguising himself as a Polish orphan. He encounters people who will betray him for a reward, who will beat him up or try to kill him, and he meets those, who will do and risk almost everything to help him. Jurek’s resilience is put to the ultimate test, when an accident cripples him, making it harder to find work. But he struggles on against all odds. Eventually the Russians reach his area and Jurek even finds a family where he could stay. Yet he is betrayed again, and a young man from a Jewish orphanage forcefully tries to bring Jurek back to his people and his faith.
