netflix movie from Brazil or Argentina fights involved

[ripher_apart]

I watched a movie on Netflix last night that concerned people disappearing from one part of a city.  A young rebel journalist is trying to find out the truth and she gets an older male journalist involved. She is killed and  he carries on.... There are at least three or 4 good female vs female fights in a ring with bare knuckles and stomping on the stomach and kicking the body... so no rule fights... they were well staged and I would like to see it again, but I do not remember the name of it.....
any help would be appreciatred.
