Because the film was given an "X Rating" it means that this trailer cannot be shown on television or in a cinema... apparently. 

The film is based on a novel by G.M. Coronel, about a group of spirit communicators who attempted to exorcise the Manila Film Center, "the rushed construction of which reportedly left more than a hundred workers buried alive in 1981." The aforementioned spirit yappers head in, to try to have a chat with some of the passed workers. It doesn't go well... 

The producers will be hoping the hype leads to a cult following anyway.
