If you have access to Netflix you might have come across the film 'Mercenary'. If you haven't seen it, I can recommend it.
It is a French film, set largely in the area around Agen. It is fictional (but perhaps not very) and deals with the seamier and unseen side of professional rugby that exploits young players from the South Sea islands. Well worth the watching I thought.
I'd be interested to hear the views of others.
