When Slater knocks Freddy down, he and Carla are forced to run when the two thugs appear, who turn out to be Freddy's bodyguards. Slater and Carla run back to their room at the Stardust. In the girls room, Zack explains everything to Kelly and she forgives him. Next, Carla tells the gang that Freddy wants her and all of them dead because she knows that he is in town to steal the Considine Diamond. Lisa gets Kurt to help smuggle Slater and Carla out of the hotel by putting them in a luggage rack. But when they get to the hotel's main entrance, Screech, returning from his escort assignment, knocks over the luggage rack, exposing Slater and Carla. So Zack grabs Screech and the four of them get into Slater's Bronco. Freddy's thugs commandeer a taxi and take off after them, followed by Kelly, Lisa and Kurt in Lisa's BMW. A car chase ensues. Zack, Slater, Screech and Carla abandon their Bronco in a traffic jam at the end of Fremont Street and escape by hiding out in a wax museum by impersonating waxwork figures. But on the street, the four are spotted again by Freddy's thugs who chase them into a casino. The guys and Carla sneak into a Las Vegas dance show dressed as showgirls. But backstage, they are all captured by the thugs as well as Lisa, Kelly and Kurt who stumble by. The gang is taken to Freddy's room where they fail to talk their way to freedom. But, Kurt suddenly announces that he is the son of the Stardust Hotel owner and he tells Freddy that he can get him to the diamond. Freddy still refuses to let any of them go and he forces Kurt to take them to the vault where the diamond is. Kurt opens the vault, and when Freddy and one of his thugs go in, Zack, Slater and Screech once again pull off their "Three Stooges" routine and trick the thug guarding them. They push him into the vault and the gang locks Freddy and his two thugs in it. After everything is resolved, the gang immediately goes to the nearest wedding chapel for Kelly and Zack to get married, they happen to go to The Silver Bells Chapel, which is run by Bert Banner. Just as he is about to marry them, Derek and Melanie Morris burst in. They tell them that Slater had earlier called them and convinced them to respect Zack and Kelly for what they are doing, so they have a change of heart and now support the wedding.
