A 13-year-old girl and a masked killer with a scythe make a pact to escape a building neither remembers entering, and somehow that becomes the most honest relationship in the story. Rachel has nothing but questions; Zack has nothing but a weapon. What grows between them isn't romance or redemption. It's two people deciding to trust each other in a place designed to break trust entirely. The building keeps its secrets, but it can't keep them from wanting to survive together.
Rachel wakes in a concrete basement with no memory of how she got there. The abandoned building around her is a maze of locked doors and shadowed corridors, each floor hiding new horrors. When she stumbles across Zack, a scarred man wielding a massive sickle, something unexpected happens: instead of becoming her executioner, he becomes her partner in survival. Together they climb upward through the building, floor by floor, encountering twisted inhabitants and psychological traps designed to break them. But Rachel and Zack share something darker than fear, a mutual understanding that binds them despite the violence surrounding them. As they progress, questions mount: Who trapped them here? Why can't either remember their past? What is this building really for? The atmosphere grows colder with each ascending level. Zack's past as a killer and Rachel's fragmented memories hint at a connection neither fully understands. What starts as two strangers fighting to escape becomes something far more complicated, blurring the line between hunter and hunted, victim and accomplice.
