When Zoey and Kiki, two irrepressible girls from another galaxy, land in Lightning Point, their dreams of surfing the waves of Earth's oceans have finally come true. But when Luca finds the key to their ship, the Plasma Card, they're forced to enlist the help of local teen Amber to get it back – a twist with explosive results!

When Zoey escapes the washing up to recharge her energy, Amber and Kiki think nothing of it – until a big burst of lightning strikes their house. Rushing upstairs, they find Zoey gone. When another bolt of lightning hits the house and tries to communicate with Kiki, she comes to a dark conclusion – Zoey is trapped in the lightning! Luca’s alien hunt has stepped up a notch now that another electrical storm has come to town – the same type of storm as when aliens first visited Lightning Point. After Kiki and Amber lose track of the storm, they realise that to find Zoey, they will have to team up with Luca. Can the girls find Zoey without revealing their secret? Or will time run out when the storm – and Zoey – are blown out to sea?

Brandon is finally ready to learn who he truly is. As Zoey speaks to him, she becomes more and more convinced that Brandon has secrets locked inside his memories. Meanwhile, Seargent Mitchell is on the alien trail – and is dangerously close to Brandon’s secret.
