Bertha and the Wolfram [Bertha en de wolfram]

Bertha loves to draw. She needs help in her daily life for she has a rare disease that impairs her vision. But Bertha refuses to be discouraged. She has organised an exhibition together with a well-known painter. The proceeds will go to research into her disease, the so-called Wolfram syndrome. Can Bertha tame the wild wolves in her life?
