The movie is mostly in a shopping mall.I think it was in another language/french/italian not sure.It was 100% a DvD not a series.I saw it in 2002-2009 really can’t recall.. it could have been filmed in the 90’s but really doubt it.So the main character is a famous clothes seller and he is in some kind of competition with a man there also a seller.He is kinda famous with the girls there and has sex with one of them after having dinner with her in the mall.Anyhow later he is in the changing room and he gets in a fight with the other seller/might have been his boss actually not sure.The boss/rival gets accidentally killed by him as he pushes him into a mirror and his neck gets pierced on it somehow.But a girl saw him/she is kinda ugly and then starts to blackmail him for sex and i thing she wants him to marry her as well.Later they/she alone? butchers the body and burns it.In the end the mall burns down i can’t recall from what but she is in the end seen as a rich woman signing autographs or something.
