Mate, please... What do you want to learn in 10 minutes? Be serious... People spend years on learning openings. French is complicated.

But well, to the question: if you have no idea about french and your opponent is familiar with it, you have 2 choices: a) play exchange variation

[FEN ""]
1. e4 e6 2. d4 d5 3. exd5 exd5 4. Bd3 Bd6 5. Qf3 Nf6 6. h3 O-O 7. Ne2 Be6 8. O-O c6 9. Bf4

The point is to exchange darksquared bishops because white's one is a bit worse than black's one. It's a tiny tiny tiny tiny plus. If you manage to get an ending with a Knight vs lightsquared bishop you have chances to win.

The other choice is... play something crazy. Go for 1. b4 or 1. f4 or 1. g4. There are many "unusual" variations around. You know, he knows* french, you don't. It's better to get unusual position that you both don't know or even you know a little bit about.
