Turf

It's the story of four buddies, four French pals: The Greek (oesteopath), Fifi (who lives with his mother, concierge), Fortuné (a West Indian who works at Cogex), and Freddy (big-time gambler). They constantly hang out at Le Balto, a Parisian betting agency. Tired of losing the little they've got, they want to stop playing the horses... But, as the well-known race betting saying goes, "a loss today predicts a win tomorrow," and luck finally strikes.
Luck which comes in the guise of a great shark, a legendary gambler, known by everyone at all the racetracks and by all bettors... and by the Vice Squad: Monsieur Paul. This "gentleman" now back in the game and proposes that the four pals purchase Torpille, a crack horse, in reality an old nag. Given that they are four, they decide to buy a leg each!
The Balto gang then enters the rarefied world of horse owners, the scams of millionnaires at racetracks from Auteuil to Monte-Carlo.
Will they triumph or lose everything, even their friendship? The horses better get trotting!
