When Jess meets five-year-old Daisy and her mum, Morag, in a local London park, they seem a perfectly happy and loving pair. Until Daisy whispers four little words that send ice seeping down Jess's spine.
Determined to save Daisy, Jess becomes obsessed with unearthing Morag's secrets. As she digs ever deeper, her friends and family start to question her own increasingly paranoid behavior.
But Jess knows what she heard and she's certain the fear in Daisy's eyes was real. Of course, she isn't imagining things...Or is she?
