In an alternate universe where dinosaurs weren't wiped off the planet, the Apatosaur Arlo (plastered all over the promotional artwork) teams up with a Neanderthal child to find his way
home as we predicted, but the
journey there and back is shockingly filled with violence, death, regret, envy, drugs (I'm not joking, Arlo and Spot mistakenly eat bad fruit and subsequently hallucinate some strange
shit), and bittersweet happiness.
