Taylor has a vision of Uncle Charlie in trouble at the Hidden Valley. She and the gang travel there, only to realise that the valley is trying to keep them out and that they are being relentlessly pursed by Raquel.

When Taylor, Meesha and Nori embark on an expedition to collect Uncle Charlie's secret buried chest, they find themselves in an ice cave under Rock Island where they encounter another Nori who's travelled from the future!

A mysterious noise is heard throughout all of Rock Island and as Taylor and the gang investigate, they are met by a girl who claims to be Lila's biggest fan. But nothing is quite what it seems - about the eerie noise or Lila's unexpected fan.
