Set in the world of fashion and PR, immature fun-loving mother Edina Monsoon and her best friend Patsy drive Eddie's sensible daughter, Saffron, up the wall with their constant drug abuse and outrageous selfishness. Numerous in-jokes and heavy doses of cruel humour have made this series a cult hit in the UK and abroad.
Edina collects Saffron from prison, where she served two years for (unknowingly) providing asylum seekers with forged passports. Saffron later invites a former cellmate, Baron, to the house, but it is soon revealed that Baron was once Patsy's drug dealer and Patsy still owes her £50,000; Baron refuses to leave until the debt is repaid. In order to obtain the money, Saffron convinces Patsy to claim her pension, forcing her to own up to her actual age. Realising she has no official documents, Patsy begins to question her own existence until Mother presents Patsy's old Post Office savings book. After going to the benefits office with Edina, Patsy successfully pays off her debt to Baron.
When Saffron berates Edina for being lazy and incompetent, Edina and Patsy decide to impress her by booking her favourite French film star, Jeanne Durand, to perform at the Royal Albert Hall. However, they are dismayed when Jeanne refuses to sing aloud and instead merely mouths the lyrics. As a solution, Jeanne lip-syncs to Bubble's vocals on the night of the concert.
Edina decides to rent out her house to Michael Douglas during the Summer Olympics, hoping it will lead to prestigious A-list parties, even though Patsy—who now needs incontinence pants—no longer shares Edina's penchant for partying. However, Bo and Marshall arrive instead, after Michael gave the couple his party invitations. Frustrated with her dwindling social life, Edina happens upon one of Michael's invitations, allowing her and Patsy to attend a pre-Olympics party. The pair are eventually escorted out after Edina harasses Stella McCartney.
