In the not-so-distant future, a spacecraft pilot named Mills finds himself on an exploration mission that quickly turns into a nightmare. After a catastrophic accident, his ship crash-lands on an unknown planet that, to his surprise, turns out to be Earth... but 65 million years ago, during the height of the dinosaur era.
Wounded and trapped in a prehistoric world filled with dangers, Mills must confront his hostile environment and, worse yet, the creatures he once only saw in history books. With the help of Koa, a young survivor who also became caught in the disaster, the two form an unexpected bond as they struggle to survive amidst enormous predators and the chaos lurking around every corner.
As they try to find a way to escape and reunite with their families, Mills must leave behind his previous life and confront his fears and traumas. The relationship between him and Koa deepens, uncovering courage and hope amidst the chaos. Every step they take reveals the beauty and danger of the planet they are trapped on, as they face the threat of a world that, although familiar, is completely alien to them. With each obstacle they overcome, Mills not only fights to get back home but also to redeem his past and secure a future for both of them. Survival has never been so intense.
