Lopez as a battered wife who escapes her abusive husband with her daughter and goes into hiding. With huge financial resources and a bunch of mafia like goons behind him it is only a matter of time before the husband tracks Lopez down.
As a last resort, Lopez goes to train with a martial artist who trains her to be able to fight back against whatever attack her husband may throw at her. When her training is complete Lopez goes with the intention of actually beating him to death but later learns that her humanity will not let her do it.
I felt a lot of the movie is a little far-fetched to rate it higher, otherwise I would have given it four stars. Lopez does toughen up in the movie (a la Linda Hamilton in Terminator II) and gives a totally different persona than she normally shows.
