Woman Seeking Vengeance
I saw this film on TV years ago. I think I saw it when I was a teenager (so late 2000s/early 2010s). The crux of the film was that a woman was seeking vengeance for her dead parents who were killed on a vineyard. At some point she teams up with a younger man who is likewise seeking to avenge the death of someone himself. As irony would have it, the woman is aided in her quest for revenge by the people who killed the person the young man is trying to avenge. I think the man who killed the person close to the young man was an older Irish mob boss. I also remember a scene of the woman smashing someone over the head with a wine bottle from her parents' vineyard.
The film MIGHT have been set in LA, and the vineyard MIGHT have been in France. I almost 99% certain the woman seeking vengeance was English.
