Vigilante film

A vigilante film is a type of movie that tells the story of someone who takes justice into their own hands by punishing people who have done wrong. They do this instead of waiting for the police and courts to do it. Usually these stories involve people who need justice but are unable to get it through the normal channels, so they decide to take matters into their own hands. In the end, they use their special skills to solve the problem and usually bring justice to the situation.
