Saffron (Julia Sawalha) meets at home with her fellow students to plan a school report while her mother, Edina (Jennifer Saunders), floats upstairs in the new aquatic isolation tank she's ordered from Los Angeles. This being Edina, of course, she doesn't brave the iso tank alone; best pal Patsy Stone (Joanna Lumley) is also there, chain smoking as usual. After the gruesome twosome crash Saffy's study session to coo lasciviously at Danny (James Lance), an uncharacteristically cute new addition to the girl's nerdy social circle, Patsy heads off after the young lad. Edina then throws a typical tantrum in order to elicit an invitation to attend Saffy's presentation at the school. Threatening to adopt a Romanian baby if she doesn't get her way, Edina even goes so far as to phone her usually empty-headed personal assistant, Bubble (Jane Horrocks), who has become a crisp, efficient force of nature ever since meeting with an occupational hypnotist. When Bubble vanishes, leaving word that "the goods" from Romania are on their way, Eddy shrugs it off and heads for the school, which Saffy has graciously allowed her to visit. Whisked off for a school tour with the headmaster, Patsy and Eddy flash back to their own school days, when Eddy got Pats in trouble for getting it on with a male student named Tony (Tim Woodward). When the headmaster of Saffy's school turns out to be the very same Tony, the old flames get hot and heavy -- right in the classroom where Saffy is giving her presentation. Meanwhile, a woman from the adoption agency arrives, several dark-haired orphans in tow. But with all of this going on, who could that be floating in Eddy's isolation tank? Originally broadcast on BBC 1 on December 3, 1992, Absolutely Fabulous: Iso Tank marked series one, episode four of this popular Brit-com.
