One Night at McCool's (2001)

On an ordinary night, in an ordinary part of town, a beautiful young woman walks into a bar. Her name is Jewel, and before long she is chatting to bartender Randy. The pair leave together, but he ends up getting into a tussle with her criminal boyfriend, who she then shoots dead, later persuading Randy to take the rap for her. But this isn't the end of it, as both Randy's cousin Carl and the detective assigned to the murder case also fall for Jewel's charms and find themselves caught up in the ensuing events. It seems that any man who meets Jewel falls instantly in love with her, and she's going to use this fully to her own advantage, leaving a trail of havoc in her wake. It also seems that she is going to get away with it - that is, until Randy decides to hire a hitman...
