On the anniversary of Uncle Charlie's disappearance, the gang are shocked to see the Bermuda Queen flying over the island. But when their investigations lead them to a hidden airstrip, Taylor and Lila accidentally get trapped on a perilous flight.

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!
