The main conflicts revolve around power struggles and betrayals among the three women: Simone, her sister Devon, and Simone's boss Michaela “Kiki” Kell. Devon arrives to bring Simone home to care for their father with dementia, but Simone resists and betrays both her sister and Michaela. The story explores how each woman compromises morals and breaks rules for power, leading to tension and transformation over a single weekend on a secluded beach estate.

Simone starts as a live-in assistant to Michaela, living a luxurious lifestyle she seems addicted to. Over the course of the series, she becomes increasingly inauthentic, hiding secrets and betraying those close to her. By the end, Simone replaces Michaela as the new Mrs. Kell, symbolizing her full transformation and ascent to power, despite the personal costs and fractured family ties.

The coastal island estate is the primary setting where the story unfolds over a single weekend. It serves as a glamorous but isolating backdrop that heightens the psychological tension and power dynamics between the characters. The estate, including Michaela’s bird sanctuary and the site of the annual summer gala, symbolizes both luxury and the fragile facades the characters maintain.

Key themes include power, privilege, manipulation, betrayal, and the compromises people make for self-preservation. The series also explores family dynamics, especially between sisters, and the impact of secrets and lies on relationships. It delves into the intoxicating and destructive nature of social climbing and the cost of maintaining appearances in a high-society environment.

The relationship is strained and complex. Devon arrives hoping to reconnect and bring Simone home to care for their ailing father, but Simone is distant and evasive. Simone ultimately betrays Devon by aligning with Michaela’s husband Peter and making their relationship public, leaving Devon isolated and forced to figure out her life alone. Their bond deteriorates as Simone prioritizes her new life and power over family loyalty.
