Two sisters, Martha and Helene, stand in focus of Dennis Todorovic's second feature film «Schwester Weiss». As mother superior of a franciscan convent, Martha leads a deeply religious life of strict rules and high morals, Helene is an atheist and was always the wilde one in the family. After one of their fights, Helene decides to put an end to her eleven year old daughter's Maja contact with her aunt Martha, fearing the sister's strong religious influence on the child. Martha prays for god's guidance for her beloved niece. But a car accident changes everything. Helene loses both Maja and her husband Theo, but also all memories of them and her past. Martha tries her best to take care of Helene, but Helenes amnesia seems to last. When Martha finds out that Helenes mother in law, Dolores, is planning for an atheistic forrest funeral for Maja, it is just too much for her to bear. She puts all her efforts into stopping this 'heathen' funeral from happening. Grief, a sense of guilt and the loss of power are driving Martha into a deep crisis of faith. Helene, however, seems to be content with her new life and the fact that she cannot grieve for someone she doesn`t remember.
