What was the name of this film on Netflix (description)?

I have been looking for a film I watched on Netflix for 3 days, it was about an ex-soldier whose family was shot before his eyes. He now lives alone and takes in a boy who sells drugs for a gang. He meets a girl who is kidnapped by the gang. The ex-soldier trains the boy until he becomes a good fighter and they free the girl.

I suspect that I saw this film on Netflix because the film was not on my YouTube purchase.

Netflix also shows the history or not?

That's how I found the film, thank you ^^
