Limbo

Friday night. London's financial metropolis. A deserted office building. Four strangers in an elevator, eager to escape for the weekend. Suddenly, the power goes out. The elevator stops dead. They hang in darkness, waiting for help. Tensions mount. They turn on each other as they realise they are stranded. Worse than that, they start to realise they are not alone. There's someone else in the pitch black elevator shaft. And he's coming right for them.
