In The Endless Staircase, an ordinary set of stairs becomes a labyrinth without end. Jason, exploring an abandoned office building, steps onto the fire escape—only to find himself trapped in a nightmarish spiral where the higher or lower he goes, the less sense reality makes. Each step pulls him deeper into a shifting maze of shadows, haunting noises, and the unsettling feeling that something is always following him.

What begins as curiosity quickly turns to terror, as Jason realizes there is no escape. Other victims have come before him, leaving behind skeletal remains and crude maps, but no way out. As the staircase twists time and space, Jason is forced to confront his fears and the truth that this isn't just a physical trap—it's a psychological descent into madness.
