At the top of a skyscraper, a group of employees from a company find themselves trapped in an elevator after an unexpected blackout. With each failed rescue attempt, the atmosphere becomes tense and oppressive. The diversity of the group highlights their different personalities: from the ambitious businessman eager to escape and get back to his career, to the young intern who is simply looking for an opportunity to shine. As the hours pass and claustrophobia begins to affect their minds, rivalries and secrets start to unravel.
Amidst the chaos, Eleanor, a brilliant but socially inept engineer, takes the initiative. With her knowledge of safety systems and elevators, she becomes the group's beacon of hope. However, they soon discover that the situation is not just a simple inconvenience; something darker is lurking in the shadows of the elevator. Starting with small incidents, fears and paranoia transform into desperation as supplies begin to dwindle.
While some of the trapped individuals try to remain calm, others fall into despair. As the tension escalates, so do the difficult moral decisions. It will be a struggle not only for survival but also to maintain their humanity in a space that increasingly becomes a psychological trap. Will they manage to escape in time, or will they become just another part of the building's dark history?
