In 1959, Sammy, a green sea turtle, hatches on a beach in Baja California and is attacked by a seagull.
He manages to escape along with another hatchling sea turtle named Shelly, who was also attacked by another seagull.
As Sammy is sleeping, the waves push the raft he is on into the water, carrying it away with him still on it.
The next morning, Sammy befriends a leatherback sea turtle named Ray, who also hatched the day before.
Ten years later in 1969, the raft suddenly collapses, leaving Sammy and Ray without their home.
Sammy, Ray, and hundreds of fish are caught in trawl nets and separated.
Hours later, Sammy is thrown back into the sea unconscious but gets saved by a dolphin.
Sammy makes it to shore and, the next morning, finds himself in an enclosure, taken in by hippies led by a woman named Snow and a French cat named Fluffy.
Eventually, Sammy shares the enclosure with a larger turtle named Vera and brings her into the enclosure, thinking that Sammy and Vera should mate.
Some time later, Vera is released back into the sea and the unauthorized hippies are evicted from their beach by the police, leaving Sammy behind.
Sammy returns to the ocean, joined by Vera.
On a food search, Sammy and Vera run into a female turtle who is being chased by a shark.
Sammy and Vera rescue the female turtle, who turns out to be Shelly.
Sammy asks Shelly to travel the world with him, stating that he has learned of a secret passage and wants to find it.
Sammy notices a ship nearby heading toward a place in the distance. Sammy and Shelly follow the ship and they made it to what they assume is the secret passage.
When the pair is about to get through it, they are separated after trying to pass through a lock.
While searching for Shelly, Sammy travels to Antarctica, where he encounters a whale and asks her for some help.
However, the whale accidentally draws attention to a Green Warrior ship full of whalers when one of them fires a harpoon at her, only for the whale to dodge and the harpoon hits the refrigerator Sammy is on instead.
Sammy, who is freezing in the water, is rescued by Green Warrior workers.
As he is being rehabilitated, Sammy reunites with Shelly, who is also being treated for frostbite.
Soon after Sammy is released back into the ocean, he reunites with Ray and rescues her from being trapped in a container.
Sammy and Shelly get married and leave to journey around the world.
In 2009, Sammy and Ray watch Sammy's hatchlings scramble across the street from their nest to get to the water.
Sammy intervenes to help his youngest hatchling, who is struggling to get out of the nest, and watches him get to the ocean.
