Lauren gets invited to a really cool party and wants to bring Danny. At first, Harry doesn't want them to attend but relents as long as they call him every hour on a huge World War II walkie-talkie. As soon as they arrive, Lauren and Danny learn from the hostess, Summer, that their adult supervisor drank too much alcohol and is unconscious. Lauren meets a new friend, Noah, and Danny fights for the reputation of a girl he likes, Olivia. All of the guests—except Noah, Lauren, Danny and Olivia—get inebriated. Without Lauren's and Danny's knowledge, Harry, Ellie and Mark sneak into the party to check on them. Even though they are shocked at the drunken teenagers, Harry and Ellie are proud of their children's conduct.
