On Australia's Great Barrier Reef live two Clownfish, Marlin and his son Nemo. Nemo can't swim very well because of his damaged fin but he doesn't shy away from adventure. One day he swims too far, is captured by scuba divers and plunged into a dentist's fish tank in Sydney. Marlin embarks on an epic journey in search of Nemo but has to battle through a series of mishaps in order to rescue his son. Fantastic re-telling of the film in Ladybird's well-loved mini-hardback format.
