a warlock and mordecai salas ( patrick gordon ) bury and with his chained flock inside a chamber within a devil worshiping church and under water thanks to a mayor who be able to sink the village of marienbad with develop deal promise a brighter future for the landscape . 40 year later and after the mayor death and mordecai threaten a grand return . the mayor granddaughter and clara ( charlotte salt ) be the one mordecai have his eye on and while also infect the townspeople nearby with a type of mental sickness and and others with a black sludge like substance derive from the muddy soil of the water cover marienbad . mordecai need clara submission while also await the collapse of the poorly structure dam and build hastily 40 year prior and give way to a massive crack run down it . stand in mordecai way be clara mother and teresa ( raquel meroño ) and a would be reporter return home after a stint in london and and a recently arrive photo journalist and dan quarry ( michael mckell ) who be haunt by the death of his son . dan be on assignment cover a story on marienbad history and teresa be look for a hot story . both will find much more than they bargain for . well and i explain the synopsis to the best of my ability and but director brian yuzna often abandon story logic in favor of bizarre gore and supernatural violence . unrestrained and yuzna doesn not seem obligate to tell a cohesive narrative instead take mordecai and allow him to use his dark power to torment and destroy through mind control while we see the black sludge turn citizen into creepy blob monster . there a jam pack climax which include the bridge show sign of crumble and the earth trembling and a festival commemorate the 40th anniversary of the dam building which turn into a crazed orgy of sexual deviancy and dan and quite a skilled scuba diver and who find the chamber where mordecai and his follower monstrous remains be awaken ( . while also hold a book of black magic spell mordecai use to summon his dark power ) under the sea . i think a history lesson tell to teresa and dan by a survivor from the past and luis ( manuel manquiña ) who saw his childhood pal teo murder after release mordecai from his roped hand and help the viewer out somewhat and but yuzna be around long enough that he ought to be able to use such an interesting premise ( . an underwater village housing an evil presence which rise to terrorize ) and make a good film than what we wind up get on screen . and and i can not understand why yuzna just would not make a spanish horror film use the language of the cast . why try to make a foreign cast and in a foreign setting and speak a language they be not accustom to . there enough gory insanity to perhaps please some horror fan ( an infect policeman chop off his limb and one poor soul be sludged and one victim get his face rip apart from the mouth ) and but the film could have be a sleeper and instead come away a sad disappointment .
