Marlin is a fretful clownfish who’s spent his life trying to keep his only son, Nemo, safe, but when curious Nemo is scooped up by a diver and whisked away to a dentist’s aquarium in Sydney, Marlin sets off on a daring, hopeful adventure to get him back. Along the way he’s joined by Dory, a bubbly blue tang with a forgetful brain and a heart of gold, and together they tumble through comic mishaps and wondrous ocean sights—rubbing noses with surprisingly friendly sharks, bouncing through a glowing jellyfish forest, catching a breezy ride with Crush the sea turtle, and even hitching a strange but helpful trip inside a whale—while Nemo, bright and determined, rallies the quirky Tank Gang to hatch a clever escape. The journey turns into a warm, funny lesson about bravery, friendship, and trust: Marlin learns to loosen his fins, Nemo proves he’s braver than anyone guessed, and the family reunites with laughter, splashes, and a bigger, braver kind of love.
