Walter Falter is a shy night moth. He prefers to stay in his quiet attic. But within Walter lies a fiery passion: at heart, he is a drummer. The only problem is that Walter doesn't have a drum set, let alone a band. The moth idolizes Marie Käferchen, his idol. At one of her concerts, the unimaginable happens: Walter himself steps into the spotlight. Kai Lüftner weaves the story of someone who seemingly flies under the radar in daring rhythms. Wiebke Rauers sets the stage for our timid hero so compellingly that one would want a Walter Falter autograph.
