am finding a movie , but i forgot the name of the movie and the stars and crew , but i remember the story of the movie which i recall , may be from that story u can give me suggestions ..

it was like ,

a crime in a bar , the movie is fully based in an nude bar , gals were dancing , and it happened like , some killer came in the bar and started making mess all people ran out of the bar but some left , about 5 , or 6 people and they started torturing them ..

the killers made a girl nude too in the bar and she was nude for much longer time in the movie , other then that , there was another scene too .. it was like, the killer was smoking a cigrette , then he gave it to the people who are there in the bar , and said everyone to smoke the cigrette , and where the ash dropped he that person will be killed.

these were the scenes that i remember about this movie
hope u can find out the name of this movie ...
other then that , the movie was entirely shooted in the bar ,
