Homo Erectus

Ishbo, Adam Rifkin, is the younger son of Mookoo, David Carradine, the tribe’s steadfast leader, and he grows up in the long shadow of his physically formidable brother, Thudnik, Hayes MacArthur. While his peers rely on brute strength, Ishbo’s mind dreams bigger: he wants to turn clever ideas into real inventions that could lift his people beyond simple sticks and stones. Yet every attempt is stymied by the meager, fickle materials available and a tribe that isn’t ready to back an unconventional path. The tension between brains and brawn shapes his every move, even as he stores a deep, unspoken wish to prove his worth.

Ishbo’s heart is tied to Fardart, his childhood friend, whom he quietly adores. When he finally musters the courage to confess, tragedy unfolds in a world where caveman norms still rule. Fardart is, to Ishbo’s dismay, clubbed by Thudnik and soon after betrothed to him, sealing a fate that leaves Ishbo with a hollow ache and a stubborn determination to find another way to matter.

After this crushing moment, Ishbo’s frustration deepens when a mammoth hunt goes spectacularly wrong. He tumbles into a great pile of mammoth dung, is swallowed by the beast, and, after the hunt finally ends, is expelled in a fantastical sequence that unfolds as animated cave drawings. The tribe’s peril intensifies when a hostile rival tribe, the Binadraks, threatens their homeland. In a swift, brutal arc, the Binadraks attack, Mookoo dies in the line of duty, and Fardart is captured—having disguised herself as a man to fight beside her people—before being hauled away.

With his father gone and his world upended, Ishbo chooses to strike out on his own to rescue Fardart. He narrowly escapes Thudnik’s wrath, and along the journey he becomes separated from his tribe, losing his way and stumbling into a surprising encounter with a tribe of Amazon cavewomen. At first, they see him as a threat, but they quickly become intrigued by his stance against the routine clubbing of women. The Amazons offer him freedom—on one startling condition: he must impregnate all of them, beginning with their Queen, Carol Alt in a dramatic, morally charged twist. At first he’s tempted by the chance to have a powerful new role, yet his heart remains true to Fardart, and he cannot go through with the proposition. The Amazon riders up in anger, and he is forced to flee their lands, chased by spears that sing the legend of conquest.

When Ishbo finally reaches the Binadrak camp again, the scene shifts as he spots Fardart. To his surprise, she does not wish to be rescued; she has adapted to her captors, living with comfort, good furs, abundant food, and a bone necklace that signals a life quite removed from the one Ishbo envisioned for them. The pursuit intensifies as the three groups—the Binadraks, the Amazons, and Ishbo’s own tribe—join the chase. They finally herd him toward death at the edge of a cliff, where he delivers a final, reflective monologue that addresses the audience as if inviting them into his world before he meets his fate.

The film’s closing image transports us to a modern museum, where a guided tour introduces schoolchildren to a caveman exhibit. The guide, Lin Shaye as the Museum Guide, leads them past a life-sized model of Ishbo, explaining through fossils how scientists reconstruct prehistoric life—often with a candid, humorous eye. In the guide’s words, the exhibit reveals a man who was “short and fat.” Yet as the guide steps away, Ishbo breaks the fourth wall once more, addressing the audience directly for a final, lingering moment that echoes the film’s blend of myth and memory.
