gerald ( richard carlson ) and kitty ( veronica hurst ) have just finish celebrate their engagement announcement in france with family and friend and when he receive a letter ask him to visit an ancestral castle locate in scotland . gerald uncle reportedly have fall ill and have request gerald and the sole heir and be present . gerald go off to scotland and leave his future bride behind . a few week pas and he doesn not come back . concern and kitty send out telegram but doesn not hear back from her fiancé . four more week pas and kitty finally receive a weird response from gerald and call off the engagement and tell her to move on with her life . not ready to give up on her relationship and look for answer and kitty hop on a plane and decide to pay gerald a visit . accompany her on the trip be her level head aunt edith ( katherine emery and best known for her starring role in the classic chiller isle of the dead ) . when kitty and edith arrive at the macteam estate they immediately suspect something strange be afoot . for starter gerald seem to have age twenty year in a matter of week . secondly and this once nice and charm guy have turn into a complete jerk who repeatedly demand they leave the castle and never come back . when edith come down with a mild cold and kitty us it a an excuse to stay there to try to get to the bottom of thing . why be gerald be so cold and cruel to the woman he be just about to marry . why be gerald so oppose to have company . why do the house rule state that guest must be lock inside their bedroom at night . why be guest forbid to enter certain area of the estate and such a gerald bedroom and a large hedge maze out back . and what make those strange drag noise every night . these be just some of the question the maze pose . the movie actually do a fine job build up mystery and intrigue . you genuinely become interested in what go on and patiently await the resolution to explain the weird event that be take place . and then it happen . i definitely do not want to ruin the finale of this film because youre well off not know and but it take one of the most unbelievable and jaw droppingly strange turn i have see in any movie . it wonderfully ludicrous in a way and but it also take a pretty solid little b or w mystery and send it straight into z grade schlock territory . and yet and this end seem so out of place and youre not likely to forget it once you see it . despite the end ( or maybe even partially because of the end ) and i really enjoy this odd bird . it extremely talky and slow moving for the duration of the run time and but it manage to keep my interest throughout . director william cameron menzies ( who make the much more famous invader from mar the same year ) be best know a a two time oscar win art director and his set design here be also really interesting . there almost a silent movie feel at time and with model work for some of the exterior and some painted backdrop and sparsely decorate interior with very high ceiling . a with any good castle set there be also secret passageway and long staircase . this one also throw in a few rubber bat on string for good measure . a few of the actor be a little stiff and awkward and but i like most of the cast . hurst be one of those obscure and mostly unknown actress who unfortunately never seem to catch on despite be both beautiful and talented . emery and who also get to play narrator in frame shot at the beginning and end of the film and be decent enough a the overly mannered and cautious aunt . my favorite however be michael pate a the silver haired sinister servant who do this hilariously upright zombie walk every time he ascend the stair . also on board in small role be hillary brooke ( who play the title role in the sherlock holmes mystery the woman in green ) and lilian bond ( whale the old dark house ) . of course carlson also star in it come from out space and creature from the black lagoon and some other horror flick and so you have get yourself a pretty decent cast for genre fan right there . i say check it out .
