For centuries, the last remnants of humanity have lived in a city sealed within an impenetrable glass wall, safe from the devastation that erased the rest of the world. No one has entered. No one has left. Until now.

When a bloody handprint appears on the outside of the wall, fear and curiosity grip the city’s inhabitants. Dr. Harper, along with his adoptive children, Takeda and Irene, joins an expedition beyond the barrier, determined to uncover the truth about the world they were taught no longer existed. Meanwhile, back in The City, Eve—a woman who chose to stay behind—begins to unravel secrets buried beneath the city, ones that challenge everything they believe about their past and their survival.

As the team ventures into the unknown, they discover that the world outside is not as lifeless as they had imagined. An old enemy waits beyond the wall—one responsible for humanity’s near extinction. What was meant to be a salvage operation becomes a battle for survival, forcing them to question not just who their true enemies are, but what it truly means to be human.

Two paths. One truth. And a choice that will decide the fate of the last city on Earth.
