An orphaned brontosaurus named Littlefoot sets off in search of the legendary Great Valley. A land of lush vegetation where the dinosaurs can thrive and live in peace. Along the way he meets four other young dinosaurs, each one a different species, and they encounter several obstacles as they learn to work together in order to survive.

Littlefoot and his friends find life in the Great Valley a bit too restrictive under the watchful eyes of their overprotective parents. Wishing to not be treated like babies anymore, the group chase after a pair of dangerous dinosaurs stealing an egg from Ducky's nest. When the egg they bring back hatches in the valley, the friends are surprised to find a baby Sharptooth. Rather than abandoning him, they name him Chomper and attempt to raise him as one of their own.

A huge meteorite has plunged into the Great Valley, cutting off the water supply and causing tension among the once-peaceful dinosaurs. While the adults argue and turn against one another, Littlefoot and his friends venture out to find a new source of water, only to be constantly bullied by a trio of older dinosaurs. The journey becomes a fight for survival when the group is cornered by a pack of Velociraptors and trapped by a sudden wildfire.

Littlefoot’s grandfather falls gravely ill, and the only hope for his recovery is the "Golden Night Flower" found in the treacherous Land of the Mists. Along with his loyal friends, Littlefoot embarks on a journey to retrieve the cure, joined by a shy newcomer named Ali, a long-necked dinosaur from a migrating herd. As they navigate the foggy, swamp-filled terrain, they are hunted by a pair of predators—a sharp-eyed bird and a massive crocodile—and must overcome their mistrust of the unfamiliar environment.
