Paige White and Hannah 'Zanna' Zagalo used to be inseparable.

After a fated meeting at university, the glamorous Zanna invited aspiring journalist Paige to write for her blog and social media channels as Zanna's rise to influencer fame beckoned. Together, they lived the #dream, moving in together and making riches from Zanna's online persona. But when Zanna tragically died, Paige reluctantly took over the Life of Zanna page - a ghostwriter emerging from behind the scenes.

Five years on, Paige is invited to take part in a documentary about the social media star's murder, and her piling bills and lavish lifestyle mean she can't possibly afford to turn it down. But then she receives a strange email, a note that just reads: 'I know what you did.'

As the cameras turn on Zanna's family and friends, old rumours start to resurface. Is Zanna's murder all it seems? Or does someone have something to hide?
