What is the plot?

Olivia begins the season by meeting women who market themselves as MILFs and GILFs, including a 71-year-old named Caroline who hopes to use the demand for sexually attractive grandmothers to help pay off her mortgage. The episode stays focused on how these women package age, confidence, and desirability into a paid sexual persona, with Olivia observing how explicitly they tie their earnings to their image and presentation.

The second episode shifts into cosplay, where Olivia enters a world where costume play and adult content overlap. She meets creators who make money by dressing up and filming sexual material, then tries to find her own cosplay alter ego as she watches how fantasy, character choice, and visual branding shape what sells.

The third episode moves to what the series describes as the XL body market, where Olivia meets people who have monetized larger body types in an industry that treats bigger bodies as a fetishized niche. The episode includes her trip to Las Vegas to meet Marilyn, a size 24 woman who has earned a fortune from a fetish for big and beautiful women, and Olivia sees how the performers use confidence and self-presentation to turn their bodies into a commercial asset.

The fourth episode takes Olivia into financial domination, or findom, a world presented as promising high returns for relatively little work. She explores the dynamic between the person giving commands and the person paying for control, and the episode emphasizes the transactional structure of the arrangement as Olivia witnesses how money, humiliation, and obedience are turned into the product itself.

The fifth episode sends Olivia to the United States to investigate the top earners on OnlyFans, where the show says only the top one percent of more than three million creators are making substantial money. Olivia meets adult content creators who have reached that elite tier, and the episode centers on the scale of the earnings gap and the business side of maintaining top-level demand.

The final episode focuses on the "boyfriend experience," where men are paid to offer romantic attention, companionship, and sexual services. Olivia meets the men profiting from this demand and the women paying for it, including arrangements that can extend from nights of passion to sending soiled underwear by post, and the season ends by showing the breadth of the niche and how it is sold as an intimate fantasy rather than just a sexual service.

The final episode is The Boyfriend Experience, which centers on money made through the "boyfriend experience," including sending soiled underwear by post.
