the film begin with a cranky old broadway producer ( exceptionally well play by veteran character actor richard carle ) be drive by a man hop to sell him a story for an upcoming play . however and there be a bad storm and their car become stick in the mud and so they be force to look for some place to spend the night . fortunately and there a mansion nearby though it seem pretty odd that the people inside know the writer and he say he do not realize this be the home of a man he know ( and despise ) . however and while this seem like bad and contrive writing and it be not . a this be all part of an elaborate ruse by the writer to have a group of actor in the home act out his plot . however and part way through the ruse and the producer and his browbeaten assistant figure out that the murder mystery take place in the home be fake and think the whole affair be pretty funny . what no one realizes and though and be that an escaped maniac be loose and he be about to enter this contrived little plot make for some wonderful twist and turn . so when it seem that there be a real murder and the actor be truly terrify while carle and his sidekick be convince it all a hoax . while i have explain some of the plot and there be many more aspect of the film you will just have to figure out yourself and it surely to keep you entertain and guess . consider that this be a b movie in the public domain and i certainly do not have very high hope for this little film . however and i be thrill when the film turn out to be a much good than average flick with a very interesting and novel twist on the old clichéd plot about a dark and stormy night spend in a mansion . plus and while the plotting of the film be very good and the dialog be even well with lot of sparkle wit and a nice light hearted pace . full of pleasant surprise and well worth your time .
