The woman filming and talking in the video appears to speak with the Argentinean accent, suggesting the video could be from Argentina, according to Best Gore member @artyomka.
Said woman films a man lying on the sidewalk. The man appears dazed, and is blooded. His lower right leg is broken with a bone sticking out. The woman asks the man what he did to end up like that, but no real indication is provided whether his compound fracture was the outcome of an accident or an attack.
Thanks a lot for the video @artyomka:
