Nemo, an adventurous young clownfish, is unexpectedly taken from his Great Barrier Reef home to a dentist's office aquarium. It's up to his worrisome father Marlin and a friendly but forgetful fish Dory to bring Nemo home -- meeting vegetarian sharks, surfer dude turtles, hypnotic jellyfish, hungry seagulls, and more along the way.

Dory is reunited with her friends Nemo and Marlin in the search for answers about her past. What can she remember? Who are her parents? And where did she learn to speak Whale?
