Act 1: The Yagahl Tribe

The story begins in a remote and mountainous region, where the Yagahl tribe lives a simple and nomadic life, dependent on hunting mammoths for survival. The tribe’s existence is threatened by dwindling food supplies and the harsh environment. Among them is D’Leh (Steven Strait), a young hunter who dreams of earning respect and winning the heart of Evolet (Camilla Belle), a beautiful orphan with striking blue eyes and a mysterious past.

D’Leh’s father, who abandoned the tribe years earlier, is regarded as a coward, casting a shadow over D’Leh’s life. The tribe’s wise shaman, Old Mother (Mona Hammond), prophesizes that Evolet will play a crucial role in their future, further complicating D’Leh’s feelings for her.

Act 2: The Raid

One fateful night, a band of fearsome warriors on horseback, known as the “Four-Legged Demons,” attacks the Yagahl village. They kill many tribe members and capture Evolet along with several others. Determined to rescue Evolet and his people, D’Leh, accompanied by his loyal friend Tic’Tic (Cliff Curtis) and a few other warriors, sets off on an arduous journey across treacherous landscapes.

The group encounters various dangers, including harsh weather, wild animals, and hostile tribes. Along the way, they befriend a tribe of saber-toothed cat hunters and gain new allies. D’Leh’s leadership skills and bravery come to the fore, earning him the respect he longed for.

Act 3: The Civilization of the Gods

Following the trail of the captors, D’Leh and his allies discover a massive, advanced civilization ruled by a god-like figure known as the Almighty (Tim Barlow). This society is responsible for the enslavement of various tribes, including the Yagahl, and is building monumental pyramids using slave labor.

Evolet is held captive in the heart of this civilization, destined to become part of the Almighty’s harem. D’Leh learns that the Almighty’s power is based on fear and superstition, and he devises a plan to incite rebellion among the enslaved tribes. With the help of his allies, D’Leh stirs a revolt, leading to a climactic battle against the Almighty’s forces.

Act 4: The Revolt

The final act sees D’Leh and the united tribes storming the pyramids, freeing the slaves, and confronting the Almighty. In a fierce battle, D’Leh manages to kill the Almighty, exposing him as a mortal man and shattering the myth of his divinity. The pyramids are destroyed, and the enslaved people are liberated.

D’Leh reunites with Evolet, who was fatally wounded during the battle. In a mystical and emotional moment, Old Mother’s prophecy is fulfilled as Evolet is miraculously healed by a mysterious force, symbolizing the triumph of hope and unity over tyranny.
