The film starts with the narrator saying “Once upon this same earth, Beneath the same sun, Long before You, Before the Ape and the Elephant as well. Before the Wolf, the Bison, the Whale, Before the Mammoth and the Mastodon in the time of the Dinosaurs” when a drought is occurring and some dinosaurs are heading to the “Great Valley”, an area with lots of leaves. A “Longneck” (Apatosaurus) herd gives birth to a single baby, named Littlefoot (Gabriel Damon).
One day, Littlefoot comes across Cera (Candace Hutson), a “Three-horn” (Triceratops), practicing head butting while trying to smash a Beetle with her horn. Littlefoot thinks it is funny and Cera challenges Littlefoot who accepts and the two children charge headfirst toward each other until Cera’s father, Topsy (Burke Byrnes), intervenes and as he gets annoyed with Littlefoot, he meets Littlefoot’s mother (Helen Shaver) who meets him as they depart.
Littlefoot’s mother explains to Littlefoot the different kinds of dinosaurs: “Three-horns, Spiketails, Swimmers, Flyers” and that they’re different and it’s always been that way, but she promises Littlefoot that there will be other longnecks for him to play with in the great valley. That night, as Littlefoot follows a “Hopper” (Frog), Cera plays with Littlefoot for a while until a “Sharptooth” (Tyrannosaurus Rex) (Frank Welker) attacks.
During their escape, Littlefoot accidentally blinds Sharptooth in one eye with a thorn. Littlefoot’s mother intervenes, battling with Sharptooth and suffering severe injuries, but managing to defeat him by pushing him into a deep chasm. At the same time, an “earthshake” (earthquake) occurs, opening a deep ravine in the ground, which swallows up the Sharptooth and a great deal of other dinosaurs, and separates many herds, including Littlefoot’s and Cera’s. Littlefoot finds his mother when the earthquake ends, but she is mortally wounded, and near death. Before dying, she tells Littlefoot that she will be with him and gives him instructions on how to get to the Great Valley. She instructs him to follow the “bright circle” (sun) past the “great rock that looks like a longneck” and then past the “mountains that burn” (volcano).
Cera finds Sharptooth’s body, and thinking him to be dead, pokes fun at him until he awakens, having only been unconscious, causing Cera to flee in terror. Littlefoot meets a “Bigmouth” (Saurolophus)[dubious – discuss] named Ducky (Judith Barsi), who asks to join him. As they travel, and try to find food along the way, they encounter an aerophobic[original research?][verification needed] “Flyer” (Pteranodon) named Petrie (Will Ryan), who joins them on their quest. Cera bumps into them and warns them of Sharptooth, but Littlefoot does not believe her, since he is convinced that Sharptooth is dead. As Cera describes the encounter (exaggerating her bravery), she accidentally flings Ducky near a patch of grass, which has a hatching egg containing a baby “Spiketail” (Stegosaurus). Ducky names him Spike and brings him into their group.
Sharptooth attacks them in the morning, but they escape through a cave-tunnel too small to admit him, and discover the Longneck-shaped monolith mentioned by Littlefoot’s mother. Although they pass other landmarks she mentioned, such as a string of volcanoes, Cera grows impatient as the search begins to yield no results. She quarrels with Littlefoot, causing a schism in the little herd following a fight between the two. Littlefoot continues in the direction he was told, while the others follow Cera, who goes another way as she wanted to (against Littlefoot’s wishes). As Ducky, Spike and Petrie fall into danger involving lava barriers and a tar pit, Littlefoot comes and rescues them. They find Cera being harassed by a pack of Pachycephalosaurus, and, having been coated in tar, scare them away. Ashamed and humiliated, Cera, still unwilling to admit that she had gone the wrong way, goes off to be alone.
Later, while frolicking in a pool of water, Littlefoot and his friends spot Sharptooth off in the distance. Surmising that Sharptooth cannot swim, Littlefoot formulates a strategy to defeat the carnivore by luring him into the deep end of the pond, using Ducky as bait, so that he and Spike can use the large rock on top of a nearby cliff to force him into the water. The plan nearly fails when Sharptooth leaps on top of the boulder, until Cera rejoins the group, allowing Littlefoot and his friends to push both Sharptooth and the boulder off the cliff and into the water below. Sharptooth nearly drags Petrie down with him, but Petrie manages to escape.
Littlefoot then follows a cloud that looks and sounds like his mother. Her cloud leads him to the Great Valley, where the children’s surviving relatives are already settled. Littlefoot calls to his friends, and tells them they have found the Great Valley. Petrie and Ducky rejoin their families, and Ducky’s family adopts Spike. Cera reunites with her father, and Littlefoot joins his grandparents. The friends happily run around, and splash in the rivers. The group then races to the top of a hill and they hold each other up as the narrator closes the film by saying “And they all grew up together in the valley. generation upon generation, each passing on to the next, the tale of their ancestor’s journey to the valley long ago”.
