Overwhelmed by fear after losing his wife, the clownfish Marlin raises his only son, Nemo, with suffocating overprotectiveness on a reef in the Great Barrier Reef. When Nemo is captured by a diver and ends up in the aquarium of a Sydney dental office, Marlin sets off on a desperate journey across the ocean to get him back. Along the way he is joined by Dory, a friendly blue tang with a fleeting memory, and the two encounter vegetarian sharks, surfer turtles, and swarms of jellyfish. Andrew Stanton and Pixar craft a dazzling and moving underwater adventure about parental love and the art of letting go of fear.
