While the gang set out to find their way back home, Mr. Thicknose has a meeting with the Great Valley dinosaurs to find out what cause the water to disappear from their valley.
As the gang begin their adventure to find their way home, they notice that they're in a different land they've never been and continue to a path they'll lead them back to their valley.
When they enter the forest, they encountered a angry One Horn (Sinoceratops) that doesn't like anyone in his territory and Littlefoot got badly wounded, and the gang manage to escape through safe and Littlefoot is still wounded.
After leaving the one horn's territory, they entered a huge crater where some of the dinosaurs are and knows that the water was gone too, and then they search the valley to find water and were able to find a watering hole so they can drink and then encountered 3 narrow horns (Einiosaurus) and had help from a green male three horn (Triceratops) named Sparky who has a scar on his forehead and gets laughed at some of the dinosaurs that teased him and Cera has a crash on him and then the gang were caught by the narrow horns and took them to their leaders led by Iguanda (an iguanodon) and were attacked by rogue four legged sailed back sharpteeth (Dimentrodon) and they rogues left and Torra (Torosaurus) blames Sparky and Littlefoot and his friends for leading them in the valley.
Outside of the crater, the rogues tell their leader Trake (a dimentrodon with a scar on his mouth) about Sparky being friends with Littlefoot and his friends and will get them soon.
Back at the Great Valley, Hino leads Hyp, Mutt, Nod, Guido, Skip, and Tickles on a search to go find Littlefoot and his friends.
In the morning, the gang explore around the crater and sees the dinosaurs having a meeting knowing if the sharpteeth will attack soon during the dry season Torra still blames Sparky and the gang for the mess they caused.
the help from two outcast dinosaurs like Clubber the club tail and Runni the beaked fast runner (Pelecanimimus) who stood up for Sparky before the crater dinosaurs find out that they went off.
As the gang follow the dried up trail they meet a quill tailed dinosaur (Psittacosaurus) named Quill who was stuck on a tree that fell to the cliff and Spike and Tippy saved him before the tree fell into pit and Quill joins them to find the water and Quill tells them not to say water, cause the dinosaurs around the forest might panic when the mention water, and Ducky tries asking why the dinosaurs are scared water, and Quill tells them that he doesn't know why.
Meanwhile the rogues notice that Littlefoot and the others are talking to Quill about the water and they told Trake about them, and Trake notice that they were telling the truth about Littlefoot and Chomper and one of the rogues tries to attack them, but Trake stops him, cause he see black clouds apoaching and orders his pack to return back to their head out.
As the gang stop to eat, Chomper meets a lost dinosaur that looks like Hino and discovered a lake dried up and notice that the river is dried up as well, and the gang tries to ask the dinosaurs what's causing the problem without saying water.
Later Hino and the others are still searching for Littlefoot and the gang and entered the territory of the One Horn that Littlefoot and the gang encountered and were able to get away.
Back in the forest, the gang spots a digger and ask him what happen to the lakes and rivers and the digger admits to not knowing anything but suggests they talk to the female runner. The female runner passes them to the Sailback (Ouranosaurus), who was eating treestars before seeing the gang before telling to talk to the clubtail (anklyosaurus).
As the gang meets the clubtail who tells the gang about the dinosaur who knows what happen to the dinosaurs lives in the cave by the trees, they walked in and see the dinosaur who happens to be the same digger they met before who explains he led them to the cave since it's the only place he knows that the rogues aren't hearing and watching. He warns them about the rogues' boss, Trake who been sending his pack to attack and capture the dinosaur. Llttlefoot ask the digger where they can Trake and to stop him and his pack, and the digger tells them that Trake's hideout is in the cave on the top of the falls in the woods, but he warns them that that it's full of feathered armed fast biters (Pyroraptors).
As they arrived to the woods they have to be careful if they run into any fasters and were reunited Guido, Skip, Tickles, and Hyp ,Mutt and Nod and Hino who finally found them
Later, after escaping from the fast biters the gang find the path where the water is coming and finds out that it was being blocked by lots and lots of big rocks and then notice a swimming creature coming towards them, and it turns out to be Mo who swims all the way from the big water and then they encountered the rogue four legged sharpteeth and start to fight them with the help of the little dinosaur Chomper met and Sparky and the others, and during the fight, Guido, Skip and Tickles tries to move all the rocks out of the way with Hino's help and the little dinosaur and Mo tries to move the others underwater and Chomper,and Hyp and his Buddies were able to move all the rocks and then the water starts coming out causing it to flood and the gang and the rouges got caught in it and fast biters got swept away.
The gang and their friends manage to get to dry land while the rogues meet their ends as some of them with down a water fall and Littlefoot and Trake were on the Tree Branch at the edge of the water and Littlefoot defeated Trake and managed to swim towards shore while Trake goes over the water and the tree branch caused him his death and he meets up with the others while all of the water goes towards all the valleys.
While the herd watches their home getting burn in the fire they see the water heading toward it and cools all of it down and they have Littlefoot and Sparky and their friends to thank for all they done.

When the gang return home, they see that all the water has return to valley and all the dinosaurs were all happen to drink it and Chomper decided to name the little dinosaur Nable cause Nable was able to help the gang and Mo is happy to live in the Great Valley and Cera was thinking about seeing Sparky again someday and the gang thinks Cera has a crush on him and the gang heads toward the watering to drink and cool down has the dry season ends.
