WorstPreviews are running the following as a plot summary for Ocean's 13, but does it tell us everything?

When Reuben Tishkoff (Elliott Gould) makes the mistake of building a hotel with one of Las Vegas’ most hated businessman, Willy Banks (Al Pacino), he gets cut out of the deal and ends up in the hospital after a heart attack. Danny Ocean (George Clooney) tries to help his old friend out by giving Banks a chance to restore Reuben’s share of the hotel, but Banks dismisses him without any regard. Six months later, with Banks’ investment thriving as the richest hotel in the city and the ultimate spot for high rollers, Ocean and his crew decide to bring him down. With the help of their former nemesis, casino owner Terry Benedict (Andy Garcia), who is also out to settle the score against Banks, his fierce rival, they scheme to find a way to bankrupt Banks on his casino’s opening night. This time, they are not in it for the money, but rather for revenge.
