Manchester, 1960s. Sally, a cynical 15-year-old schoolgirl, is much too clever for her own good. When partnered with her best friend, Pamela – a mouthy girl who no-one else much likes – Sally finds herself unable to resist the temptation of rebellion. The pair play truant, explore forbidden areas of the old school and – their favourite – torment posh Sylvia Rose, with her pristine uniform and her beautiful voice that wins every singing prize.

One day, Sally ventures (unauthorised, of course) up to the greenhouse on the roof alone. Or at least she thinks she's alone, until she sees Sylvia on the roof too. Sally hurries downstairs, afraid of Sylvia snitching, but Sylvia appears to be there as well.

Amidst the resurgence of ghost stories and superstition among the girls, a tragedy is about to occur, one that will send Sally more and more down an uncanny rabbit hole...
