One Million Years B.C.

Akhoba, the leader of the Rock tribe, along with his sons Tumak and Sakana, set out on a dangerous hunt. They successfully capture a warthog, which they bring back to their tribe as a source of food.

Upon returning, a fierce argument ensues between Akhoba and Tumak over the distribution of the warthog meat. The dispute escalates to the point where Akhoba is forced to banish Tumak to the unforgiving desert.

Tumak embarks on a perilous journey through the desert, where he faces formidable prehistoric predators. This harsh environment pushes him to his limits as he struggles to survive against towering Allosaurs and Saber-toothed cats.

Near death, Tumak collapses on a secluded beach where he is discovered by Loana and her tribe, the Shell people. They save him from an Archelon, showcasing their strength and bravery.

While Tumak is away, Sakana attempts to usurp his father's leadership. This betrayal leaves Akhoba heartbroken but ultimately unchanged as he withstands the challenge.

In the Shell tribe, Tumak discovers a more advanced civilization and finds solace in their peaceful way of life. His heroic act of saving a young girl from an Allosaurus wins Loana's admiration.

Tumak's spirited nature leads to a confrontation with Ahot over possession of a spear. This sets the stage for Loana to accompany Tumak back to the Rock tribe's camp, where tension awaits them.

Tumak and Loana make their way back to the Rock tribe, but they are met with hostility. This rejection juxtaposes their experiences in the Shell tribe, leading to moments of intense reflection.

As Tumak and Loana traverse the landscape, they witness an epic battle between a Triceratops and a Ceratosaurus. This encounter greatly impacts their understanding of the world around them.

A fierce competition arises between Loana and Nupondi, culminating in a dramatic duel. Loana ultimately wins, but her mercy leaves her vulnerable to Sakana's growing suspicions about her and Tumak.

During a carefree swim, a Pteranodon swoops down and captures Loana. In an astonishing twist, a Rhamphorhynchus intervenes, leading to a struggle that ultimately ends with Loana's safe return.

The brewing conflict between the Rock tribe led by Sakana and Akhoba culminates in chaos as a volcano erupts. This catastrophic event devastates both tribes, taking countless lives amid the struggle.

In the wreckage of the eruption, Tumak, Loana, and the survivors of both tribes come together to grieve their losses. United in sorrow, they begin to reconceive their future amidst the devastation.

As the leader of the remaining community, Tumak guides the survivors on a daunting quest for a new home. The trials they faced have irrevocably changed their perspective and united them in purpose.
