Beneath the fractured ceiling of a war-torn museum, three strangers take shelter among the relics of lost civilizations.
A field doctor haunted by mercy, a soldier who no longer believes in orders, and a convoy driver who carries both a secret and a heartbeat not her own. Between them lies a crate containing humanity's first invention - a stone hammer carved 3.2 million years ago.

As explosions echo through the city, the artifact becomes more than a symbol. It is a mirror - of what they've built, what they've broken, and what might still be worth saving. Each blow against the locked door becomes an act of faith, defiance, or desperation, and the choice between survival and humanity grows impossibly thin.

HAMMER is an unflinching exploration of endurance, morality, and the archaeology of violence - a story about what remains when the dust settles, and whether the first tool humanity ever made was meant to build a world... or break it.
