What I am sure of:
- Beginning of the movie: A guy is driving in his car, he sees woman in trouble (2-3 gang members are bullying her), he helps her and beats the gang members. Later, gang finds him in his house, violate his wife and burn them both alive.
- Protagonist wants to take revenge for the killed couple and starts tracking gang members and killing them, I remember one dude was filled with concrete, another died in a car, all deaths were quite brutal.
What I am unsure of:
Genre - action, thriller, kriminal
Country - England
Protagonist was a son of killed couple, an ex-soldier, elite, which just returned from last mission in Afghanistan
Protagonist had a friend in police which was trying to convince him to forget about revenge, before he started killing gang members.
