In Finding Nemo 3 (2025), Disney Pixar brings viewers back to the underwater world for a new adventure with Marlin, Dory, and Nemo. Directed by Andrew Stanton, the third installment takes the familiar characters beyond the Great Barrier Reef and into unknown depths to face new challenges and meet a variety of intriguing sea creatures. The teaser trailer has already generated excitement by hinting at a storyline that expands the underwater universe while touching on themes of family, resilience, and the beauty of unexplored worlds.
The story begins with Marlin (Albert Brooks) adjusting to a calmer life, content with watching over Nemo (Hayden Rolence), who has grown into a confident, adventurous teenager. Dory (Ellen DeGeneres), ever curious and impulsive, is eager to explore more of the ocean, nudging Marlin and Nemo to join her in searching for parts of the ocean even she hasn’t seen yet. Their peaceful existence is disrupted when they encounter a group of migratory fish who warn them of an impending environmental disaster: an undersea volcanic eruption that threatens to disrupt the ecosystem and send shockwaves through their reef.
Motivated by the thought of protecting their home, Dory suggests traveling with the migratory fish to seek out a wise, legendary sea creature rumored to know how to prevent such disasters. Despite Marlin’s reluctance, he eventually agrees, and the trio embarks on an ambitious journey. Along the way, they meet a colorful cast of new sea creatures, including Echo, a playful, inquisitive octopus with the ability to mimic sounds (voiced by Awkwafina), and a reserved, deep-sea anglerfish named Lumen (voiced by Benedict Cumberbatch) who is both mysterious and fiercely protective of the ocean’s secrets.
As the group dives deeper into the ocean, they face a range of obstacles, from strong currents and towering underwater caverns to the darker regions of the ocean that hide dangerous, bioluminescent predators. Nemo, more daring than ever, often leads the way, impressing Marlin while testing the father’s resolve to keep his son safe. Marlin struggles with letting go and trusting Nemo’s instincts, while Dory’s short-term memory occasionally leads them into humorous but risky situations.
The climax reveals the ancient sea creature they’ve been seeking: a gigantic, mystical turtle named Tide, whose wisdom transcends generations. Tide shares the secrets of the ocean’s balance, revealing that the natural disaster is part of a larger cycle that helps rejuvenate marine life. However, they discover that human activity is intensifying the effects, and they need to find a way to mitigate its impact on the reef.
In a heartwarming resolution, Nemo proves himself by coordinating with sea creatures to guide the currents, minimizing the damage to their reef. Finding Nemo 3 concludes with a message about teamwork, environmental stewardship, and the courage to face the unknown, leaving fans with a renewed appreciation for ocean conservation and family bonds.
