Synopsis

Alicia has a surprise to celebrate her boyfriend Simon’s birthday: a romantic dinner for two in one of the almost abandoned buildings she inspects as part of her job. 
The evening starts out perfectly, but the couple soon makes the startling discovery that they are not the only “intruders” in the building that night, after Alicia witnesses a chilling act at the hands of three mysterious hooded men. On realizing that their presence in the building has not gone unnoticed, the three men begin the search for the couple, well aware that their dark secret cannot leave the building. 
It doesn’t take Alicia and Simon long to work out that they are trapped inside and unless they find a way out soon, they will be at the mercy of the sinister trespassers. As the sense of claustrophobia and hysteria heightens, Alicia and Simon find themselves in the middle of a fight for their lives. Isolated and unable to get any help from the outside, they must resort to their most basic survival instincts in order to escape the nightmare scenario that they have unwittingly become a part of.
