Follows a fearful clownfish named Marlin who, after his son is captured, embarks on a dangerous ocean journey with the forgetful Dory to rescue him from a Sydney dentist's aquarium. Marlin and Dory must overcome sharks, jellyfish, and deep-sea predators to reach Nemo, who is meanwhile attempting to escape the fish tank with the help of a local, scrappy group of fish. After overcoming multiple obstacles, the pair are reunited, and a transformed, less-cautious Marlin allows his son to explore the world with confidence.
