I saw a trailer for this film and haven’t been able to get it out of my head.  A teenage boy (blonde, curly hair) moves in with his female friend’s family. I think the family was Hispanic.  The family seems nice and welcoming at first but they’re actually horrible people.  I recall the father or uncle slapping someone in the movie trailer.  I think the boy and girl are both prostituted and/or raped.  The premise was that the boy did not lose hope or faith in humanity despite all the abuse he was being subjected to.
