The woman: Her highness J.Lo, as Slim. (That's the character's actual name, I'm not just commenting of her incredible physique.)
The victim(s): Her controlling wife beater of a hubby, Mitch, played by Billy Campbell.
The reason: You see, Mitch isn’t very nice. He cheats on Slim, basically tells her to deal with it, and explains that if she tries to leave him, he’ll make her life a living hell and/or kill her. (What a meanie, right?!) Anyway, J.Lo, nay Slim, is not about to lay down and take it. She has had enough! Just like the title says.
