Nicolas Humbert on the trail of his own heritage:Wolfsgrub is the house, or rather the hamlet, where his mother lives.A woman getting on in years, she tells of her childhood and youth in the Nazi Germany, and of her father, the Jewish writer Max Mohr. Humbert allows his mother the space and time to tell her story, portraying her everyday life with the use of concentrated images. From the narrative fragments emerges the portrait of a freethinker as well as the image of an era plus impressive and coherent evidence of the link between home (Heimat) and individual identity. Written and directed by Nicolas Humbert.
