Well if it's like the 1960 orginal it is about a bunch of old WWII army buddies who get together and using their skills from the service rob 5 Las Vegas casino at midnight on New Year's eve. The orginal stared Frank Sinatra, Dean Martin, Sammy Davis Jr., Peter Lawford, Angie Dickinson, and great supporting actors. Sinatra is Danny Ocean the "leader" of this group. It was during the filming of this movie that the "Summit" was taking place every night at the Sands Hotel. For $5.00 you got dinner and a show with the "rat pack." Those have taken on legend status in Las Vegas. I recommend renting the orginal, it's not the greatest movie, but it will entertain you. AS the end credits begin look in the background.
Today's version will probably have the buddies being veterns of the Gulf War and Clooney will play the role of Danny Ocean.
