This contains spoilers if you haven't seen the movie!

There was a film I saw in the last couple of years, it is relatively new.

I believe it was Brazilian subtitled but could have been from another south american country.

The plot is as follows: There are a series of robberies in a relatively posh area of Brazil. A couple of men volunteer to become a sort of security for the area. their motives are a bit mysterious until we realize at the end that the entire thing revolved around their plot to get revenge on a local criminal mastermind who had killed their father many years earlier.

Thank you in advance!

City of gold?
