The story takes place in the Lower Engadine where every year, on March 1st, kids chime the bells to banish winter and welcome spring. Ursli would also like to take part in the Chalandamarz, but with his little bell he would have to stay at the back of the parade. Unbeknown to his parents, he sets out in the Alp – that is still covered with snow – in search of the biggest cowbell. His adventure is on.
