Rio has to leave his home in London and go to stay with his grandmother in California whilst his mum receives treatment in a specialist hospital in London. When he discovers that his mum had once found much joy in the whales that passed by her childhood home in Ocean Bay, he has the idea that if he can get a photo of her favourite whale, White Beak, then perhaps this can help her once again find her happiness! Little can Rio know the adventure he is about to embark upon!
