Dazzling underwater animation. Marlin the clown fish loses his wife and children in a barracuda attack and only one of his offspring survives - Nemo. On his first day of school and forgetting the advice of his overly-protective father, Nemo is captured by a scuba diver and ends up in a fish tank in a dentist's office. While he tries to hatch a plan to escape and return home, his dad braves his way across the ocean to get his son back.
