A man who was injured in an accident (or was it a suicide attempt?) has a visitor in his hospital;the man suggests a strange deal:in exchange for a substantial amount of money,he will go to a hotel (Pension Edelweiss)where ,when he does not expect it,he will be softly killed ("you'll live this world like a balloon which a child releases")When he arrives,he finds six other people who apparently registers the same desire :to leave this world for a better one.A scary hotel-keeper takes care of the residents and every time an ominous music is heard ,someone gets killed .
