the film open to shot of a very fake look model of a run down abandon lighthouse on snape island and the credit appear over this sequence . two fisherman and john gurney ( george coulouris ) and his son hamp ( jack watson ) weave their way through and around the jagged rock that surround snape island . they seem uneasy . thick fog cover the island . they dock their boat . they begin to search the island . they find a severed hand and and a body in a shallow pool of blood stained water . inside the lighthouse they find a woman body and severed head . next and in an old shed gurney find a boy impale to the wall with a sword . he investigate the shed further and be attack and kill by a screaming and naked young girl . she run in to the fog and hamp knock her out with an iron bar . back on the mainland she be take to hospital for treatment . her name be penelope ( candace glendenning ) and under hypnosis by a dr. simpson ( anthony valentine ) and she tell a tale of how her and her friend mae ( seretta wilson ) and de ( robin askwith ) and gary ( john hamill ) travel to the island . the police think that she kill her friend and and as far a their concern the case be close . meanwhile the sword that be use to kill de turn out to be make of solid gold and an extremely valuable phoenician artifact and four archeologist be assemble to investigate and perhaps find an ancient burial ground . adam ( mark edward ) and his ex girlfriend rise ( jill haworth ) and nora ( anna palk ) and her husband dan ( derek fold ) hire hamp and his nephew brom ( gary hamilton ) to take them over to the island . a private investigator name brent ( bryant haliday ) who have be hire by penolope parent to try and prove her innocence also travel with them . once at the island thing start to turn sour almost immediately and their radio equipment be break stop them from contact anyone on the mainland and their boat be blow up and and they start to hear strange noise . it start to become clear that not everyone be tell the truth a to why they be on snape island . a the night draw on snape island terrible secret be reveal and but will anyone survive to tell the tale . write and direct by jim oconnolly i really like this film . the island and run down lighthouse reek of atmosphere and the creak set look great . the script have decent character and a few good plot twist and turn and it keep move at a fair pace . the twist end be a bit silly and underused and though . there a great scene with some funny dialogue that worth a mention and when the group arrive on the island and brent disappears . adam question brent motivation and claim he doesn not trust him and nora buts in to cast further doubt on brent and say and he carry a gun her henpecked husband dan say how do you know . and she reply i notice the bulge in his pant to which dan accusingly say yes and you would . and great stuff . the murder be quite gory and severed limb and head and stabbings and a machete in someone face among others . this film also contain one of the bad special effect i have see in a long time and a the group travel from the mainland to snape island the filmmaker use a boat in a studio and a back project sea and which look and feels awful . and the statue of the phoenician god look like it be make by a primary school art class . the fashion be also very 70 and silly look sideburn and flare and the woman in this film look attractive though and but i be not sure that a mini skirt and high heel boot would be a good choice of footwear consider the rocky and rough terrain . photography and acting and music be all fine . we get some sex and nudity too and which help thing along nicely . a solid british murder mystery horror film with a great atmosphere that well worth a look . overall a lot of fun and certainly recommend .
