Lembur (2014)

Tommy is a designer. He has been toiling away at a website design but his colleague accuses him of plagiarism. To Tommy's dismay, even his boss is unimpressed and hits the roof, bellowing at Tommy to rework the entire design and stay up all night if he must. Without a choice, Tommy hunkers down to pull an all-nighter in the office. Late at night with no one else around, terror strikes. Is he alone in the office, or not?
