Meet 'Drum', the orchestra drum who is feeling very humdrum. When Drum is feeling unhappy he stops playing and the entire orchestra comes to an embarrassing halt. But with the help of his friends - a cast of colourful instruments, as well as ironing mice and shaving pigeons - Drum realises that without him keeping the beat, they lose their way and that they need him to save the day!
