In a desolate future where humanity has nearly vanished, only three people remain on Earth, struggling to survive in a world that has been irrevocably altered. The story is narrated by Liam Gilespie, one of the last survivors, who chronicles his lonely existence and the downfall of civilization that led to this apocalyptic reality.

Striving to discover the truth behind their new world, Liam's adventures take him to new parts of the United States, where new struggles await.

Set in the aftermath of societal collapse, which began in the late 22nd century. After the Second Great Depression in 2136, humanity's reliance on artificial intelligence and automation led to widespread unemployment, discontent, and ultimately, violence. The fragile economy crumbled, and people turned against the very machines that once served them, smashing robots and AI systems in a desperate bid for control. This destruction marked the beginning of the end for human civilization, as the loss of AI-driven infrastructure caused a regression in technological and societal capabilities, allowing the true enemy to sweep in, in an attempt to take their hate-driven revenge.

The three survivors roam the remnants of the United States, each person keeping to their own territory, driven by mutual distrust. Despite the abundance of resources left behind by a population that disappeared almost overnight, Liam's life is marked by isolation and the constant threat of becoming the last person alive.
