The Vault of Horror

The movie begins with 5 strangers entering an elevator. It takes them to the basement and they exit to find 5 chairs a table and 5 glasses of brandy. The elevator, on that floor has no call button, so they decide to sit and wait for it to return on its own. One of the men, Rodgers states that his nightmares are quite frightening. After some coaxing he shares one of them. The nightmare begins with him speaking to his private investigator in his apartment. The P.I was hired to find Roger's sister. As soon as he gives Rodgers the address, Rodgers shows his gratitude by murdering him to cover his trail. Then, rRgers promptly travels to his dear sister's town. Before he murders her, he stops at a restaurant across the street from her. It is sunset and the restaurant is closing and the owner tells Rodgers that "they" come out at dark and that is why they are closing. Rodgers thinks it is odd but leaves and goes to his sister's house because she has just inherited everything. He fixes that by stabbing her. Then, of course he leaves and sees that the restaurant is open and "people" are going in to be seated. The food and beverages are unusual and Rodgers is soon about to learn why and meet "them", the vampires. His ending is also the end of this segment. The next man to share his dream is Critchet, an older Englishman. In his dream he is a neat freak that gets remarried in " A Neat Job". His new wife can't seem to put anything in it proper place.

The problem is that the rope involved in the trick is possessed by a spirit that does not like betrayal. They accidentally found a way to play "The Trick That Will Kill You" on themselves.
