Story summary

In 2019, Sophie Lionnet was brutally murdered in London by her then-partners Kouider Medouni and his wife Loubna Belhoussine, events that may have inspired the Lifetime thriller "The Seemingly Perfect Family." The court uncovered filmed recordings over 12 days showing the couple torturing Lionnet, accusing her of having a relationship with Mark Walton, the founder of a band called Boyzone. Authorities alleged that Medouni was obsessed with his ex-partner and believed Lionnet was involved to frame him for losing custody of their son. The movie, starring Rylee Reagan as an 18-year-old nanny who falls into danger while working for a wealthy couple, began streaming on Netflix in early 2026, quickly topping the platform's trending list despite the unclear basis of its inspiration from real events.
