Steve Martin and Michael Caine are Dirty Rotten Scoundrels, and they're absolutely ruining the Riviera. Martin is Freddy Benson, a small-time con man sleazing his way through Europe on whatever handouts he can scam. Cain is Lawrence Jamieson, an impeccably dressed and high-minded artiste who thinks Freddy is giving him -- and all con men -- a bad name. At first, Larence agrees to help Freddy spruce up his talens and his wardrobe. But when it becomes apparent that the Riviera isn't big enough for the both of them, they make a winner-take-all wager over the fortunes of a naive American soap heiress (Glenne Headly).
