Will and Holly lose their father in devastation that wrecks the Land of the Lost, but they are joined by their Uncle Jack who has been searching for them.
Will and Holly Marshall are exiting a newly-discovered pylon, with Rick Marshall still inside. As Will and Holly eat, they discuss their hopes that this new pylon will help them return home. Suddenly, a violent earthquake erupts, and Will and Holly return to the pylon, only to see Rick Marshall drawn through a time portal, and the control panel topples, spilling the crystals.
Realizing that with the pylon destroyed in the earthquake, they cannot retrieve or follow their father, Holly gives into despair. Will attempts to comfort her by pointing out that if Rick made it home, he will be working diligently to recover them from the Land of the Lost as well.
As Will and Holly go to survey the damage caused by the quake, they encounter a depressed Cha-ka, who explains that the earthquake had caused a fissure to open up in the ground, separating him from the rest of the Paku, who abandoned him. Will and Holly explain that they were similarly separated from Rick, and that until the three of them are reunited with their lost ones, they would be their own family unit.
They are interrupted by the appearance of a strange mutated elasmosaurus with two heads. After escaping the creature, the three journey to High Bluff for supplies and food, only to discover that the entrance to High Bluff has been sealed off by the earthquake.
After making a quick lunch of native fruit, three three begin journeying in search of a new cave to make their home. But Holly spots something fall into the Land of the Lost by the lagoon and the three set out to find what it was. Cha-ka climbs a tree to investigate, but can only describe the object as big and yellow, not recognizing what he saw. He also notes that the object landed in high grass by the lagoon.
As they approach, they again evade the elasmosaurus, which Holly dubs Lulu ("one 'Lu' for each head"). The fact that they dodged Lulu twice in as many encounters prompts them to theorize that the creature probably has poor eyesight when its heads are out of the water. When Lulu retreats, they approach the high grass and discover that the "big yellow" object spotted by Cha-ka is a life raft.
As they approach, they discover that life raft's owner is their paternal uncle Jack, who has been searching for them for the last six months, ever since they disappeared. He had followed their route and entered the Land of the Lost following an earthquake the same way Rick, Will and Holly did.
Their reunion is interrupted by the reappearance of Lulu. After the Marshalls and Cha-ka flee, Will sends Holly and Cha-ka to gather food while Jack and Will explore options for a new home. The Lost City, they decide, would not be suitable as the Sleestak and Big Alice still occupy it. The Lost Temple, however, seems to be a good choice. While the door had been previously sealed off, the earthquake unsealed the entrance.
Jack and Will then gather firewood and, as night begins to fall, are working to make the place more suitable to live in. They are interrupted by the cries of Holly as she and Cha-ka return, pursued by Sleestak. After the Sleestak are driven off, the voice of the Sleestak Leader is heard, demanding the surrender of the temple. The Marshalls refuse, and the Sleestak renew their assault.
While the Marshalls and Cha-ka take turns keeping the Sleestak at bay with torches, Jack and Will are able to mount the heavy stone door on rollers. Finally, the Marshalls and Cha-ka are all able to get inside with the door sealed against the Sleestak.
