It's Fashion Week season; London's over, and New York's due up next. A fortuitous time, therefore, for Gran to let slip that Serge is gay and living in the Big Apple. Eddy resolves to track him down - after all, how many gay men can there be in New York?

Edina finds herself between jobs after selling off her companies and is retraining Bubble as her full-time Personal Assistant.

Patsy, meanwhile, is busy with her brand new job as Chief Design consultant and buyer for the ultra-hip fashion concept store "Jeremy's". Saffron is busy making observations for her writing project and Edina, in her loneliness, turns her attentions to her long lost son, Serge.

Saffron will not give her information about Serge's whereabouts and Serge's father, Edina's second husband Marshall and his Californian wife Bo are similarly tight lipped. Edina's Mother, however, lets slip that Serge is in fact gay and living in New York.

Eddy is thrilled as she and Patsy are about to go to the Big Apple for fashion week - although Patsy is less than keen for Edina to find her runaway offspring. Edina finds a card in Saffron's room that leads her to a Gay/Bisexual/Transgender support centre in New York called 'Guff'. There, Edina is forced to marry Patsy in order to bribe Serge's contact details from psychiatrist and caseworker Goldie.

Edina initially mistakes the flambouyant Martin for her son, but finds that Martin is Serge's partner, and Serge is a conservative male version of Saffron who works in a second-hand bookshop. Serge resists Edina's attempts to reconnect, eschewing her narrow definition of what it is to be gay - loud and flamboyant, and still sad that she and Patsy once burned all of his books.

With Martin's help, however, Eddy convinces Serge to spend a day with her and Patsy at the fashion shows, where he is given a makeover and meets his Godmother, Debbie Harry. After the shows, Edina, Patsy, Martin and Serge go club hopping and Serge sees Martin joining his mother and Patsy in the exact kind of decadence that he ran from twelve years earlier.

When Patsy and Eddy send a bar up in flames by accident they are arrested. However, Saffron posts bail and they return home without Serge - but Edina reveals that she has adopted Martin.
