In the fall of 2015, Israeli director Ronit Kertsner finds a YouTube video that is shared more than 70,000 times. It shows Hans Breuer, a Jewish migrant shepherd who drives an Arab family across the border to Austria and sings a Yiddish lullaby to the children to calm them down. For more than three years, she accompanies his extraordinary life and dedication to refugees. REFUGEE LULLABY portrays the inner world of a multi-faceted person who tries to come to terms with his own mental traumas while helping others.
