Rhythm is spontaneous and experiences life as movement; and all sound as music. Glas loves life smooth and stable; and prefers things to remain the same. When Rhythm and Glas meet at Bellevue park they have the five days of half-term to see if their friendship is worth keeping once they go back to their separate schools. Will they find a way to create something remarkable; a rhythm that is theirs alone? Through music and movement and mishap these two young people experience the difficulty and joy in connecting with those unlike themselves.
