Nothing happens or all the same happens again and again so you're trying to follow a pseudo thriller which isn't one and suddenly it fizzles out! The setting is the same,oppressing ,always in the same construction site. There are a few main characters who hardly talk to one another and at one moment we think there is a clue but it leads to nowhere. It could have been a short film since the length doesn't provide any more information but boredom. Actually, the trailer is largely enough since everything is in it. I was definetly disappointed and the trailer is just a fraud. It is not a thriller at all as it was sold.
