Nemo is a curious and impressionable six-year-old boy who lives alone with his overprotective, single-parent father, Marlin. Having led a sheltered life, Nemo brims with the excitement of starting school and finally seeing the wonders of the Great Barrier Reef. Despite being born with a withered fin, Nemo yearns for adventure, and as fate takes him far from home, he learns he is capable of doing great things…like his father.
