After waking up with a throbbing headache, Edina 'Eddie' Monsoon scrambles to get ready for a high-profile fashion show. Her critical daughter, Saffron, who had urged Eddie to stop drinking, is quick to chastise her mother for her reckless behavior. Edina's loyal friend, Patricia 'Patsy' Stone, arrives to help her head to the office. There, Edina's assistant Bubble reveals that top model Yasmin Le Bon has pulled out, and Princess Anne has taken Princess Diana's spot on the guest list. Undeterred, Edina cleverly secures attendance from several lesser-known celebrities, leading to an unexpected triumph. That evening, Edina and Patsy embark on a wild night of drinking, infuriating Saffron, who retaliates by locking Edina out. The following morning, Edina and Patsy concoct a scheme to convince Saffron that Edina will be entering rehab.
