In the short film My Grandma is an Activist, filmmaker Tobias, like many young people, often feels powerless in the face of the world's problems. His grandmother, on the other hand, is tirelessly active: she demonstrates with the climate movement, helps refugees find housing, and writes protest letters to the city council. During his burnout, Tobias turns to her for advice, with pressing questions like: "How can I make a difference? Does it even matter?"
