Brandon and Andrea discover that the school board has quietly passed a measure in which any senior found drunk at the prom will be barred from graduation. Jackie tells David and Kelly that she has sold the house. Brandon and Brenda do not plan to attend the prom. Brenda accepts an invitation from football star Tony Miller, and Andrea calls Brandon at the last minute after Jordan gets the flu. Donna is surprised when her mother gives her permission to stay out all night. David rents a hotel room for the night. Mel serves champagne at a pre-prom party, and everyone except Dylan and Andrea drinks. Donna gets drunk (partially because she also hadn't eaten all day) and becomes very ill. The gang tries to sneak her out of the hotel, but she faints right in front of Mrs. Teasley. Brandon and Andrea check out a hotel room that Tony had presumptuously reserved, and Andrea gets a little carried away.
