A young woman heads to a hospital for a routine checkup ahead of an upcoming job promotion, expecting a speedy visit. However, her simple medical consultation unexpectedly morphs into a nightmarish ordeal. The hospital seems oddly deserted and eerie, and she is subjected to a series of unsettling and seemingly unnecessary tests. As she tries to comprehend the bizarre situation, the woman becomes increasingly anxious to leave, but finds herself trapped in an ever-tightening web of hospital bureaucracy and confusing directives from the staff that prolong her stay.

As the woman's anxiety escalates, it becomes clear that something much more sinister than a series of medical mishaps is at play. The once familiar hospital transforms into a labyrinthine prison, with the woman's past eerily weaving into the fabric of her present predicaments. Shadowed by strange occurrences and the haunting sense of being watched, it dawns on her that a deranged figure from her past might be orchestrating this twisted game. The haunting memories that she worked so hard to bury now threaten to engulf her in a deadly reality, as she struggles to unravel the connection between her current terror and the shadows of her youth before it's too late.
