I think this is the best Mexican action movie ever.
OK, I am student of acting and I recommend you this movie because of:
1: Amazing acting of Barbara Mori and Alejandra Barros. 2: Story and screenplay are really good and very well written. 3: All genres in one movie, like you're watching drama, then thriller, then crime, in some moments romance...so good. 4: The end. Unpredictable. 5: You don't need more reasons to watch it.
If you like to watch movie, and think about who is resposable for all of things that's happened to her like you're reading book full of mystery. It's him, hmmm or her...no, no definitely it's this one and on the end you was wrong.
