>>99314745A bunch of thugs break into Paul Kersey's house after he beats up one of their gang during a mugging gone bad. They abduct his daughter and she throws herself out a window rather than be raped. Kersey goes on a vigilante spree.
The Charles Bronson Death Wish franchise is basically a character profile of Kersey's slow descent into Frank Castle-esque vigilantism. Initially it's about getting revenge for his family, over time it becomes about justice and making the world seem sane, by the later films it's an addiction, a neverending war he can't walk away from.
Really underrated series.
