'What are we, Papa?' the toy mouse child asked his father. 'I don't know,' that father answered. 'We must wait and see.' So begins the story of a tin father and son who dance under a Christmas tree until they break the ancient clockwork rules and are themselves broken. Thrown away, then rescued from a dustbin and repaired by a tramp, they set out on a dangerous quest for a family and a place of their own - the magnificent doll's house, the plush elephant and the tin seal they had once known in the toy shop.
