Some Ground Rules...

Emily (portrayed by Laney Grey) apprehensively steps into the workspace of a youth refuge worker, Donna (acted by Penny Barber). It quickly becomes apparent that Emily is with child, but uncertain about whether to keep the baby, considering her current situation of homelessness. Donna, while consistently compassionate during their exchange, discloses that she and her spouse, Alex (John Legendary), are attempting to adopt, but are facing hurdles.
That's when Donna suggests that she could look after Emily in her own home -- covering all costs -- throughout Emily's pregnancy, on the condition that Emily consents to let THEM become the baby's legal guardians. Emily is taken aback but seizes the chance. Nevertheless, Donna cautions her about their house's strict regulations, but Emily isn't discouraged, agreeing to everything in her thrill.
The following day, Emily moves in with Donna and Alex, eager to witness how her life will transform from then onwards. But she's not ready for the shock of seeing Donna and Alex welcome her in their birthday suits. That's when they disclose that they are naturists, a detail they purposely omitted earlier to avoid frightening Emily away.
Though Emily initially feels uneasy, she can't let this once-in-a-lifetime chance slip through her fingers. When they establish some basic rules, including Emily's need to embrace the naturist lifestyle herself, she complies. She's confident that she'll adjust to the change in due course.
Emily is unaware of the additional stipulations that are yet to come.
