Premier are beginning one of their busiest periods: the September Show Season, kicked off, as every season, with New York Fashion Week. Business for the bookers table means organising their models for shoots, catwalk shows and castings, as well as the day-to-day running of the agency and liaising with 'walk-ins', models' parents, scouts, foreign agents, designers and photographers.

Carole attempts to find some new talent ahead of London Fashion Week. There is tension in the office between the commercial booker and his boss.

There is conflict in the office at the height of the show season.

Following the argument between Carole and Chris over booker John's walkout, John ends up coming back to the office to talk it out with his bosses. It is Men's Day in London Fashion Week and the pressure is on.

With up to 20 city-wide castings a day to find female models for London Fashion Week, the booking staff feel stretched to the limit. They also have to cope with some of the girls' behaviour and pull out all the stops to locate a Japanese model who cannot speak English and has got lost in the middle of the night

Following the chaos of London Fashion Week, the staff move to Paris where a model is on the brink of stardom. She opens one of the leading shows and books her first major fashion shoot for Italian Vogue. Elsewhere, a girl who decided to give up her modelling career has a once-in-a-lifetime opportunity as world-famous photographer Mario Testino asks to meet her for a possible campaign for a well-known fashion brand

The agency decides to drop some of the models from its books, two of the new girls face a few home truths, and founder Carole White talks candidly about her relationship with Naomi Campbell. Last in the series.
