why have ramón ( carlos fuentes ) bring his five college mate to a spooky abandon school building which use to service the black sheep child of wealth . that answer might just lie in a diary in his possession supposedly write by his die father . what they come in contact with be in fact a relived episode involve another group of six and with five of them presumably meet graphic fate at the hand of a sadistic security guard ( paul naschy ) which occur 20 some odd year ago . but and a they seek out a way to escape from this place and terror await them a that horrify moment in time replay a the group run for their life and often in state of panic a the killer begin to hunt and destroy them in a various bloody way . will ramón and any of his pal survive this night of horror or become ghost forever repeat the very same night like those before them . stylish spanish slasher have that professional gloss and potent and shock violence to match . some witty exchange between the character . layer in their dialogue be pop culture reference to american horror film which might annoy some viewer . a demented naschy be really ferocious with the kiddy a he attack them gleefully . quite a bloodthirsty maniac who carry out his violent act with relish . i find the loud musical cue a bit annoy and the filmmaker often use flashback from previous event in the film a reminder to the audience . i do not think these trick be necessarily need and but felt the director wish to communicate in depth with the viewer hence the use of cue and flashback . a minor diversion for this film plot keep move and the camera follow the pace of the character and how they react to the chaotic situation present to them . your enjoyment of this film may ultimately come down to your acceptance of the paranormal supernatural aspect of the plot . moment in time relive and a killer who continue his work seemingly from the grave . the twist do seem a bit jarring and abrupt and but this might ( . or might not ) work consider how the story play out regard why ramón father be show amongst those ghost re enact those grisly event two decade prior . i will say that this film probably wouldn not hold up if scrutinize in detail and but a a slasher flick and it a breath of fresh air .
