Directed by Gérard Pirès — who wrote the story with the author of the book that it’s based on, Jean-Patrick Manchette, although John Buell’s novel The Shrewsdale Exit has also been cited as an inspiration in other places — L’agression is the story of Paul Varlin (Jean-Louis Trintignant), who obviously has road rage issues. Well, after some bikers hit on his wife, those very same men end up nearly killing him and his family.
Stay tuned. As Paul pulls over, he charges the three helmeted motorcycle maniacs, who knock him out and then assault and kill his wife and daughter. Yes, Paul has screwed up and he can’t admit it to himself. All he wants is revenge.
There’s also Sarah (Catherine Deneuve), the sister of Paul’s dead wife, who realizes that her brother-in-law is going about this as badly as you can imagine. He’s no Paul Kersey. She even saves them both at one point, as she’s a better physical fighter — and maybe even mental — than he is.
Pirès went on to make the comedy series Taxi in France. There’s no hint of that in this movie.
