Kate, a quiet boarder, making some risky choices to pursue the experimental music she loves. Clem, shrugging off her old swim-team persona, exploring her first sexual relationship, and trying to keep her annoying twin, Iris, at arm's length. Ady, grappling with a chaotic family, and wondering who her real friends are; she's not the confident A-lister she appears to be. When St Hilda's establishes a Year 10 Wellness Program in response to the era of cyber-bullying, the three girls are thrown together and an unlikely friendship is sparked. One thing they have in common: each is targeted by PSST, a site devoted to gossip and slander that must have a source within St Hilda's. Who can you trust when rumour is the new truth?
