Plot

Rick is transported back to the real world just as his brother Jack arrives searching for the family. The Marshalls' cave dwelling is destroyed in an earthquake, so they take up residence in the temple at the Lost City, much to the chagrin of the Sleestak.—Anonymous

A quake hits the Land of the Lost, which brings about many changes. A new two-headed dangerous looking dinosaur emerges from the lagoon, the creature which Holly names Lulu. Luckily for them, Lulu seems not to see well out of the water, which makes it easier for the Marshalls to elude it. Cha-Ka has been separated from the rest of the pakuni by a chasm in the ground that broke open, Cha-Ka on one side, the other pakuni on the other. But most importantly for the Marshalls who were working at one of the pylons where a known time door exists, Rick falls through the time door to parts unknown - hopefully to home - leaving Will and Holly alone. Will and Holly decide to form a new family of sorts with Cha-Ka. And what they have called home since they arrived in the Land of the Lost has caved in, and with the cave-in all their possessions are buried. They need to look for a new home, they believing the temple at the Lost City might be a good place if they can get the door open. The quake however may have others thinking the same thing. On their way to the temple, Holly sees what she believes is someone falling out of the sky probably through the same time door they originally fell through. That person or creature may be a friend or foe, which they won't know until they investigate.—Huggo
