When Ben doesn't follow the rules and loses a large sum at one of the tables, Micky is less than impressed and tells him that he must be reimbursed $200,000, and they will all return to Boston early.
Ben gets the others together - he knows they don't need Micky. They do what they do best and stack their chips, but Micky has stayed behind and ratted them out. Cole (Laurence Fishburne) and his men walk up to Ben at the table, and he is taken away to a secret room - and beaten quite badly.
Ben returns to uni - to find that the Professor has failed him, so he won't graduate, and someone has stolen all his winnings from the dorm room. Desperate, he forms a plan -- he approaches Micky at one of his parties and proposes a deal --- they return to Vegas for one last score, before the last casino uses the new security system. They will work together to maximise their money. Micky agrees.
Ben and Micky, both disguised, are way up in chips ... before Cole and his men find them and give chase. Ben and Jill toss a bin-liner stuffed with the chips to Micky and they agree to meet at the usual place. They both run away in different directions. Micky gets into a limo and tells the driver to go to the airport instead. He opens the bag -- to find cheap chocolates. The driver opens the window - it's Cole's right hand man.
Meanwhile, Ben and Jill make it out the casino, but Cole is waiting for them. Cole thanks Ben for giving him Micky, and says his grades will be reinstated, but then pulls a gun and demands the chips as well. Ben and Jill have no choice but to throw the winnings over to him.
They return to the casino -- but as the security teams were distracted, Ben's MIT nerd buddies have taken the casino for a lot of money. There's a lot of smiling faces. So he still made money, dated the prettiest girl on campus, and has something to put on his CV.
As it ends, he finishes his story to the board member about 'life experience', and it seems pretty certain he'll earn his scholarship. Unless the next student in line was Mark Zuckerberg.
