Two neighbours live in the same house as the best friends until one of them buys a small harmonica and starts to play in a unbearable way. The other one takes his revenge and answers with some intolerable play on a lar...展开ger accordeon. They start a competition, using bigger and bigger instruments. Other neighbours join them in a dreadful ear-splitting noise. This infernal sounds provoke some unwanted consequences, all because of a small »Piccolo« accordeon.
